- Опубликовано: 15 июн 2024
- I bet many of you think that the ideal gas law must prohibit passing gas on the elevator. That's a very good guideline, but there are other important laws we must know! Like Boyle's Law, Charles's Law, Avogadro's Law, and more! Let Professor Dave run you through the details.

Better than Crash Course, if I may. Less drama, more facts delivered in a calm and composed manner.
I love both of these channels.Yeah there is much drama by Hank but information and its explanation isn't a dumb one because of that.
Legit
Aadithya Hrudhay hank makes me anxious
You dont have to put down something just to appreciate some other thing! Professor Dave is awesome and so is Hank Green. They both have different styles of teaching. Prof. Dave teaches in a calm & composite manner. Hank teaches in a more fun & hands-on kinda manner. And I think both are amazing in their own unique ways.
Composed* lol
I like the calm and concise delivery. No zany personality, no senseless entertainment gimmick. Just a solid breakdown of what, how, and why.
Gracias.
Thank You for taking a 3hr lecture and compressing it into 5 mins! You're doing great Prof!
Yeah, but he's way too fast. Don't you think so?
@@mideafinni-jegede8829 Yeah, but its also a video... you could always go back.
Yeah i do.....Thanks for the reply.
@@andynguyen6341 absolutely agreed
This is brief nd very comprehensible ....but I think you must have studied to an extent to grab this real quick....a starter won't really get it
This was explained exceptionally well! The visuals you provided along with the simple explanations made these formulas soooooo much easier to understand. Thanks You Professor Dave!
you're a mother born teacher. Your teaching techniques easily stays above all other fancy channels. Please create more series. I'm watcging many of your series entirely.
I just farted and here I ended up at the Ideal gas law.
Thank you science Jesus
this guy just saved my chemistry grade. Kudos Professor Dave!
i’m refreshing up on my chemistry as i’m planning on taking it next year in college, but i haven’t actually done anything in over a year 1/2. your videos are amazing and they’re great for getting me back into it!
thanks sir! i didn’t get it when my teacher told us about this but your short and to the point method really works for me :^D
giveyouthesun m
Same as here thanks much
I've never learned chemistry so efficiently. Your 5 min vid > a full lecture.
Thank you so much Professor Dave! I had a hard time understanding our chemistry class and this video really helps me a lot😊
Dave you are literally saving my life THANK YOU
i used to know this material when i was in university. Such a joy to have it all come back in a few minutes. And Prof. Dave is very easy on the eyes too. Love him
Professor never stop uploading videos... Because your videos are a big help... Thank you
can't stop don't stop won't stop!
Professor Dave Explains hahaha you are the best professor, no lie 😁😂
You explained this very visually and rationally. Thank you!
Another 5 minutes of pure genius.
Thank you Professor Dave !
Myghadddd U R AN ANGEL SENT FROM HEAVEN. WE HAVE A TRIMESTRAL EXAMINATION TOMORROW AND OUR TEACHER’S PPTs DOESN’T EVEN MAKE SENSE TO ME. BUT THEN I FOUND YOUR VIDEO AND FOR A SPAN OF 11 MINS (cause i watched 2) I UNDERSTOOD EVERYTHING RIGHT AWAY. YOU DESERVE A MILLION SUBSCRIBERS
🙌🙌🙌
I love your videos. Straight on point, simple and concise
Thank you, For your Precise Explanation Professor. Keep up the Good Work👏💖
I must applaud you for explaining this in a very much simple manner. Thank you professor Dave!
What a teacher! Taught me something in 5 minutes which couldn't be explained by my school teacher in 1 hour! 😆😇😈
If u listen ur teacher will also say in 5 min
Relatable
your is 1hr,mine is for years now
@@lakshmikallam8204 Not necessarily true
thanks for the explanation bruhh!!!!!
Currently enrolling in Canadian high school as an international student. My dream is to be a tutor like you in my country. You are truly an inspiring figure, Prof. Dave. Thanks for all the contents, I cannot thank you enough.
Sir Dave I love ur Explaining Style.. Awesome
You explain things so easily and simply! Thanks for saving my chemistry grade :)
You look great just like a Chemistry Messiah.
Just because the actor portraying Jesus in a movie looks like that, short hair with a beard and all, doesn't mean that's what Jesus really looks like. Only the people in his time on earth knows what he looks like lol.
@@glennmnte9488 yeah 😄😄
Doesn't mean He even exist😂
@@glennmnte9488 If you don't know what the other person is exactly talking about then better not to comment. The word "Messiah" means - A leader regarded as the saviour of a particular country, group, or cause and here she is not referring to 'jesus'.
Not look, he is
Thank you so much sir . you delivered in a calm way.
Professor Dave, you're the best. Thank you!
These videos are beneficial for everyone in the internet, I applaud your efforts to educate people!
I have one small question. How did scientists calculate the conversion between Kelvin and Celsius?
Thank you professor Dave!😌
I understood so well
Probably the best explanation of kinetic theory. Thanks prof!
This is well explained and easy to understand thank you sir
The way of your explanation is tooo good in one explanation I understand all the topic sir thank you very much for uploading this video in youtube I'm ur new subscriber you r explaining the whole topic in 5 min which my teacher explains in one hour once again thank u very much sir for uploading this video 👍🏾
That's alot you explained really nice and you made me understand without any hesitation.
straight to the point! everything is so clear. I m ur big fan
Thank you. This was real helpful.
this video was insanely helpful
always find your videos easy to understand than any other's
Ultimate clarity brother
Thank you Proff. You're a life saver
great vid , would love more comprehension questions.
Thanks... This was amazing... I'm satisfied with ur teaching...... You're better than crash course
Wow for 5 minutes I've learnt more than my lecture notes, amazing.
Amazing explanation
Thank you sir.
I now have an understanding on Gas😊
Professor you really made me understand this topic once again thank you for the wonderful work you are doing
Sir, your videos are used for our lecture! Thank you
hey dave thanks for making videos ....
Love your work
This was taught very well, thx
Thank you so much sir
Awesome and uis probably one of the best education channels
when i watched crash course i was sure i was gonna have an especially hard time with this topic, but after watching ur video i feel way more confident about all this lol
Very useful thank you!
Professor Dave, I can't tell you how much your face on a RUclips video gave me relief when I saw this in chemistry. As soon as I saw the intro I was like "Hey, isn't this the guy that completely destroyed flat Earth?" amazing. I just went back through my google classroom, and rewatching this is so much better than having to go back through all slideshows for everything. Thanks professor Dave for existing.
really interesting and easy to understand
thank you professor
Love the video keep making it.
Sir, Very nice and clear explanation I have no doubts at all thankyou so much for this lesson.
I'm B.sc Ist year student I haven't join any coaching for physics Sir, I beg to you... please make more about physics chapters plsss!!!!
very good explanation
much helpful thanks😄
This was excellent!!
This videos is really helpfull professor...
Great videos!
You make it so easy for me👍🇿🇲👏 thank you very much
You’re love professor dave❤️❤️
My students and Iove professor Dave! Always just right👩🏻🔬
great sir ....i apppreciate your skill
As a planetary astronomer dealing with atmospheres, I'm much more comfortable using SI units, a weird unit we thought up for atmosphere chemistry called the kilomole (1 kmol = 1,000 mol), and an appropriately adjusted SI value of R (8,314.4598 J K^-1 kmol^-1). But I suppose if I had to deal with amounts of gas that could fit in vessels and tubes in a chem lab, I'd use the units you use here!😁
Nice explain sir
Prof is a blessing fr. The scientific saviour
Thank you so so much
Thank you, Prof Dave. I Love you. :*
This guy is better than my physics teacher!
What a lifesaver
Thank you
Thank you! ♡
thank you prof
Hi Professor! Thank you so much for your videos!!. I have a question. Is it possible to *increase the pressure* and at the same time *not to increase the temperature* as a result of this? I think about the diesel motors (for example) that use high pressure for diesel to ignite within the piston and cause the explosion, which I think is because the increase in pressure *heats* the diesel enough as for this to explode (the increase in pressure increases, *consequently,* the temperature).
sure one can definitely keep temperature constant! compression will not always be accompanied by temperature increase. this is called an isothermal process.
thank you for replying professor! This is a bit counterintuitive to me though. I found something on Wikipedia _en.wikipedia.org/wiki/Isothermal_process_
_...Doing work on the gas increases the internal energy and will tend_
_to increase the temperature..._
it says (to me) that the increase in pressure increases the internal energy, which needs to leave the system for the temperature not to change (going to the environment as heat). So there is an increase in temperature just that the system makes up for this by releasing such heat. Is there any instance in which increase in pressure would not make us deal with heat production (for us not even to need to get rid of any produced heat?)
yes that would be an adiabatic process! and in fact, boyle's law talks about pressure and volume changing with temperature remaining constant. so it's just about tweaking the parameters.
OK profesor!! Thank you for replying!
Thanks big man ur helping me pass my science final
Thank you sir
Hey guys, I wanted to ask you something. I’m a foreign student and in my country we don’t use decimal numbers much. Instead, near whole numbers are given in the questions. therefore, we don’t need nor use calculators while solving questions. Given these circumstances, I realized I don’t really know how to do these calculations 🫠 I was wondering if the calculations in checking comprehension part require a calculator, or am I expected to be able to do the calculations without it? It’d be greatly appreciated if you could answer me 🫶🏻
Very nice teaching skils
Wow! 1M subscriber congrats 🎊🎉
2 million coming soon
good job
hey professor dave i guess u and ur team can start some kind of online courses.It would really be helful for us
sooooooooo amazing explanation!!!!!!!!!!
Sir your teaching skills are better then best
thank you
Loveeeee Yooooou,,,,, Thanks alooooooot! You are the one who makes me understand it!Loves !!!
God bless you Sir am really well understood
THANKS J!!!
I love you man
thank you very much you are great
Can someone answer this please: I work in blown film extrusion and cannot answer this question. If you have a bubble which is 50microns thick with a constant volume of 10 litres on air inside, why is it when you increase your thickness to say 100 microns the with the same volume of air in the bubble, the bubble increases in size? What is the science behind this?. Its also worth noting in blown film, we have a frost-line which is the point where the polymer has solidified and no longer able to stretch/mold. So when we take the output up, the frostline increases under the same air conditions it's taking longer for the air to cool then polymer as its become thicker.
Bro😂just explained the whole chapter in 5min
very helpful
the most simplified on youtube... short video and complete information
man you are doing perfectly, what you are supposed to.
Professor , you are awesome..
I loved the working in chemistry 🔥🔥🔥🔥
