There is a story of an aricraft training center that was doing face mask testing on a few trainees and one of the trainees mask failed and he was exposed to near full vacuum for 14 seconds. He passed out in 8 but he said the last thing he remembered was the saliva on his tongue beginning to boil as well as his eyes. Thats scary to think about.
This isn't an entirely accurate representation. This ignores the fact that all the water in the human body is either internal (in blood) or within cells. Obviously being exposed to (effectively) 0 atmospheres isn't going to be pleasant but you aren't going to get any exploding body parts a la Total Recall. The biggest concern of being in space is asphyxiation, or if you have an air supply, boiling from solar radiation. Like they said in the video, there is no means of heat convection in a vacuum, the only heat you'd be losing would be through thermal radiation. Basically you'd be accumulating heat with no means of cooling down. This is why the ISS has those big grey radiators that look like solar panels.
bromanche not boiling from the radiation, but SEVERE burns and tissue damage. What would happen to your tissue is like when you suck on a cup with your mouth, and that discomfort from pulling the blood to the skin surface is what it would feel like. Many times more magnified, though...
well in a human's case this seems very accurate cause we do have multiple pores located all over our body we also holes in our ears and anus. so yeah i can imagine that blood will come out of our pores and burst our flesh due to pressure.
wait. Why didnt they try this through a semi permeable membrane. To simulate the cappillaries in your intestines and your lungs. That way you can see how the pressure more accurately affects blood. The rest of the blood is nearly a closed system, so it should be fine.
No. You would not get cold fast. You would actually feel pretty warm as there is no medium that could draw the warmth out of you and the only way to lose heat is via radiating it. Your body would likely keep warm for some time. Also, the reaction to the vacuum is not that violent as your body is pretty strong and keeps most of the liquids under enough mechanical pressure to keep them together for some time. You can actually stay alive and conscious for some time while exposed to the vacuum. You lose consciousness as soon as oxygen starts to run out, but you will stay alive for a few minutes. What really kills you in space is asphyxiation. The diver sickness takes most of the time to long to develop to have more than a debilitating effect, if they manage to rescue you. I mean, it will suck. Really suck. But it is not a certain death sentence.
Vacuum exposure is no great picnic, but there's a key fault with this demonstration... I mean, I don't know about you, but I don't sit around with my blood typically exposed. The human skin and the rest of the body will be providing some minimum mechanical pressure. Mind you, it won't be enough to save your life, but it'll keep you alive a little bit longer.
Sure - IF you can get back into a pressurized environment. But those don't tend to pressurize very quickly. Still, you're totally right. If you were lucky enough to oxygenate your blood before going out (the old swimmer's trick,) and remembered to let your breath escape your lungs, a very brief skin-suited EVA might well be survivable. If you had pressurized goggles, you might even have been able to see in order to do something.
That is actually not boiling. It's air coming out of the liquid when the pressure is reduced - degassing. The same as a fizzy drink decarbonates. Notice that this "boiling" stops very quickly. Not that this is safer than actual boiling of blood. This will not supercool you as they say, but it'll make you full of bubbles. The same happens when a diver accends too fast. Extra oxygen in his blood just starts to bubble which leads air embolisms. Water is incompressible like all liquids so it won't expand in the vacuum of space. Furthermore, although water does boil at lower temperature in decreased preassure this lowering doesn't go infinitely because it is not the surrounding pressure that holds molecules together. And water has very strong hydrogen bonds. So there won't be any instant boiling in vacuum although it will evaporate faster. Unlike deep sea creatures that are adapted to hundreds of atmospheric pressures and actually get damaged when they are taken out of water human tissues would hold one atmosphere drop of pressure so no bubbling will occur inside the body.
Yeah, like they said, this would not happen as quickly because our bodies are a series of pressurised containers from the individual cells right up to our arteries and then our internal structure, all would hold up pretty well in a change of just one atmosphere, so we aren't going to start popping and bubbling. It won't feel very nice though, and your eyes, mouth lining, lung lining and any other heavily permeable membranes would start leaking more of your internal juices than they normally do, blinding you and making you feel like clammy as you lose consciousness.
This is the problem I had in my science classes. I know things happen because of other things happening. I cannot wrap my brain around the boiling blood thing and low pressure thing.
I'm Polish by myself and I guess that he don't have a problem with a "Polska" on a shot glass, but with the graver on the representative object, that is just not proffesional. :)
Just imagine, the strength of that vacuum is way weaker than the ever-expanding space yet people think rockets create enough thrust to move in a vacuum of immense proportions.
A 'vacuum' is just an area where there is nothing, its not a force. It is literally the easiest thing for anything to move through by definition, because it is defined as being literally nothing. You clearly have no idea what you are talking about.
I wonder if it would be this fast. Because your skin does have strength and will prevent a certain amount of swelling, which I think should allow for some amount of static pressure. Maybe thats the key to less bulky space suits, wrap people in super strong materials that prevent the body from expanding. Same job the atmosphere does.
boil verb (with reference to a liquid) reach or cause to reach the temperature at which it bubbles and turns to vapor. The temperature isn't increasing, so the blood isn't boiling, it's just air coming out of the fluid, correct?
When I read the comments , many people are thinking about will your blood boil in low pressure or not.I still think that people in space can't survive , because nobody can spend time without air.
But there is one problem, this would be blood out in the open, while your body is holding you together, we are quite tough in that regard, since a the pressure difference is not all that much if we compare diving down 3 meters in water and then getting up, it does not kill us, and that was 1bar more pressure on you, that means that 1 bar less would have similar effects, maybe harm your eardrums if your mouth is closed, but overall, we are quite strong... the pressure from our own bodies would most likely make the blood not boil as soon as we enter empty space.
Only surface liquid boils, like sweat or saliva. The main changes to your body physically would be swelling and asphyxiation which would be the most immediate danger to your survival.
This is only what would happen if you had a big gaping open bloody wound, if you repeated this experiment with water-filled punch balloons which are tough and elastic, not much would happen at all
Not quite. Boiling Point of Water at the top of Mount Everest (8848 m) is aprox. 72 C (161.5 F). Courtesy of www.engineeringtoolbox.com/boiling-points-water-altitude-d_1344.html
There is no air in space, so heat transfer would take quite awhile. So even though it is terribly cold, your heat has no where to transfer to. You would not get cold very quickly....
Yeah...you're forgetting that your blood is not in a shot glass; it is in your veins. Your body creates its own internal pressure, so your blood wouldn't boil.
How do you know.... Jk but if we have our own pressure it's not enough to stop that from happening. Plus there's other fluids in our body that aren't under pulses of pressure like our blood. And if the difference is great enough it will over come. Soooo.... You still die from blood and everything else going crazy
+FishFind3000 Source please. Here's one that says your blood mostly won't boil: www.quora.com/Without-a-spacesuit-it-is-said-your-blood-starts-boiling-out-in-space-because-of-the-pressure-differential-How-does-this-happen/answer/David-Kahana
The blood in your body isn´t 2 cl of water in a shot glass though. It is a more viscous suspension that is being pressurized by your whole body and thus doesn´t get to boiling point like demonstrated here. If you had a badly bleeding open wound, the blood in it would boil approximately like this, but not the blood that is being pumped by your heart.
Given that your body is mostly non-compressible fluid, your entire body would experience the pressure drop and any dissolved gases (such as nitrogen) would come out of suspension and your blood would "boil". This is an extreme version of decompression sickness, aka the bends.
I have to disagree with some of the comments here. your blood will boil, but maybe not as dramatically as this demonstration. I am a scuba diver. decompression is an issue. if you rise to the surface too quickly gasses in your blood and tissues expand and cause the bends. most diving injuries occur between 15 and 10 get from the surface. at 33 feet the pressure on your body is doubled. air embolisms can cause almost instant death or paralysis. and we are ending at 1 ATM. going from one atmosphere to zero would have to be much worse. you probably wouldn't explode but capillaries most certainly would. a final example, when a diver goes down he must equalize the pressure in his mask. if he doesn't, the pressure outside the mask becomes greater than the inside pressure. this creates a suction on the face inside the mask. this pressure will cause the capillaries in the skin and eyes to bust forming a bruise. it is not life threatening but it is embarrassing. it is known as raccoon face.

Everyone has heard about this story I think one day 4 people were in a deep ocean area now the pressure would kill off impact but the pressure is released quickly your blood will boil and I watched this before on a movie someone (one of the 4) had released the pressure lower and … everyone in there started boiling….its very graphic if I do say so myself there eyes popped out of socket though like 20 seconds after and they all fell over at diffrent times and the person who pulled it survived and was arrested for pelagic manslaughter and since the vehicle blew up it’s also destruction of government property since it was a job vehicle so he was charged for voluntary manslaughter and a bit of other charges since he was a corrupt cop (prior status was a diver person but he was a corrupt cop and he quit they had his body cam footage of him beating a black man out of racisimn and uh he went to jail for life since it was voluntary and it was of 4 men and they all had families and He also had exploded the vehicle and prior to that the explosion killed 2 or so pedestrians since the pressure lead is on the top off the ocean and Debra flew up and hit 2 men and the injuries were fatal one died and the other lived but paralyzed…this was a tragedy but it wasn’t nearly as bad as what someone would experience in space it would be more painful becuase there’s no oxygen so u can’t really breath and your in free fall so your moving mpwhile your insides are technically exploding.. This info is from google I searched most of this up the story I know from a movie (based on a true story all the things were true except for the characters) So hope this info is helpful!!!
I don't have the best understanding of physics or chemistry, but had been taught that you'd actually boil to death because heat could not be released due to the vacuum? Someone please clarify this for me a bit more?
it is pretty ... not correct. In fact, in space, you will not get cold quickly at all, like he said, there is no convection possible. You will lose your heat by radiation ... that will take a while before you lose a lot of heat. So no instant freeze time. For the air in the lunges, yes - but not enough - all air will rush out from ALL your body holes. Yes even the back door. For the boiling blood, well it will not exactly happened like in this glass. Probably you will have the issue in the part of your body where you skin is very thin, like eyes. But for the rest of your body, your are in close system. And a diff of pressure of 1 bar is not that extreme. Your body will be able to keep it. For examlple, going under water at 30 meters will make 4 bars of pressure on your body (and your body does not crushed on itself) So no explosion if you are exposed at 0 bar. But maybe one day, they could really do such experience with a fake animal that could mimic the human body, put it like one our in space and check the result. Temperature, lose of blood and so one ... Well actually I found that : ruclips.net/video/pm6df_SExVw/видео.html&ab_channel=SciShow

everyone has to keep in mind that the "BOILING" blood is still cold. not hot at all.
Those quotation marks aren't needed. It is still boiling (boiling simply being the point a liquid becomes a gas).
It boils because there is no air pressure holding the molecules together so the atomic bonds release....
you mean a very high peak
But is it actually “boiling”? Or just expanding?
it is boiling, boiling is expansion. Here the boiling occurs due to a drop in pressure as opposed to a raised temprature
There is a story of an aricraft training center that was doing face mask testing on a few trainees and one of the trainees mask failed and he was exposed to near full vacuum for 14 seconds.

Is it boiling or just the dissolved gasses coming out of suspension?
It is boiling. The boiling temperature depends on the atmospheric pressure. Low pressure means low boiling temperature.
Not quite. Boiling Point of Water at the top of Mount Everest (8848 m) is aprox. 72 C (161.5 F).

For water to not boil in space, it must be below -68 C. This of course makes no allowance for surface tension induced pressure.

Everyone has heard about this story I think one day 4 people were in a deep ocean area now the pressure would kill off impact but the pressure is released quickly your blood will boil and I watched this before on a movie someone (one of the 4) had released the pressure lower and … everyone in there started boiling….its very graphic if I do say so myself there eyes popped out of socket though like 20 seconds after and they all fell over at diffrent times and the person who pulled it survived and was arrested for pelagic manslaughter and since the vehicle blew up it’s also destruction of government property since it was a job vehicle so he was charged for voluntary manslaughter and a bit of other charges since he was a corrupt cop (prior status was a diver person but he was a corrupt cop and he quit they had his body cam footage of him beating a black man out of racisimn and uh he went to jail for life since it was voluntary and it was of 4 men and they all had families and He also had exploded the vehicle and prior to that the explosion killed 2 or so pedestrians since the pressure lead is on the top off the ocean and Debra flew up and hit 2 men and the injuries were fatal one died and the other lived but paralyzed…this was a tragedy but it wasn’t nearly as bad as what someone would experience in space it would be more painful becuase there’s no oxygen so u can’t really breath and your in free fall so your moving mpwhile your insides are technically exploding.. This info is from google I searched most of this up the story I know from a movie (based on a true story all the things were true except for the characters) So hope this info is helpful!!!
I don't have the best understanding of physics or chemistry, but had been taught that you'd actually boil to death because heat could not be released due to the vacuum?
Someone please clarify this for me a bit more?
Imagine putting ur head inside there
So that's how the did those effects in superman 2. Geez.
it is pretty ... not correct.
In fact, in space, you will not get cold quickly at all, like he said, there is no convection possible.
You will lose your heat by radiation ... that will take a while before you lose a lot of heat.
So no instant freeze time.
For the air in the lunges, yes - but not enough - all air will rush out from ALL your body holes. Yes even the back door.
For the boiling blood, well it will not exactly happened like in this glass.
Probably you will have the issue in the part of your body where you skin is very thin, like eyes.
But for the rest of your body, your are in close system.
And a diff of pressure of 1 bar is not that extreme.
Your body will be able to keep it.
For examlple, going under water at 30 meters will make 4 bars of pressure on your body (and your body does not crushed on itself) So no explosion if you are exposed at 0 bar.
But maybe one day, they could really do such experience with a fake animal that could mimic the human body, put it like one our in space and check the result.
Temperature, lose of blood and so one ...
Well actually I found that :

so blood boils without getting hot? Science....
