Thanks for the Vid. Would highly recommend to Check Victor Schauberger and his studys of water and Dr. Masaru Emoto study about water and Rice (Consciousness) Experiment.
About water freezing "top-down" in a body of water: that's exactly how life could've survived and developed during the gobal ice-coverings that've happened in the Earth's geological history; where the entire Earth was covered by at least meter-thick ice even at the equator, but *chemical synthesis, not photosynthesis* is how life originally got nutrients; so life on Earth is not that dependent upon the sun.
I wouldn't say "is", maybe WAS not that dependent on the sun in earlier stages, but I am not sure the energy hungry creatures we have today would've ever arose without photosynthesis.
@@AriaHarmony Well, we know from biology, including botany, that photosynthesis is more efficient; and it is natural for a lifeform to become dependent on the most efficient means of getting nurishment/food; so that naturally follows that what we've discerned to be the most likely guess would be most probable; as a niche is a lifeform's job: how it gets its nutrients.
@khanacademy In Kurt Vonnegut's novel "Cat's Cradle" Ice-9 is a substance that when in contact with water it freezes everything. Would this substance be possible based on tweaks in how the hydrogen bonds function?
I'm not sure, Mr. Khan, so you should review the video to check me on this, but it seems as though you wrote "Ice is less dense *that* liquid water." as opposed to "Ice is less dense *than* liquid water." You probably should check out my reply in this case, just to be sure. It was right about seven minutes into the video; just for an estimate.
Sal explains this so well that I grasped it playing at 1.75 speed. Amazing. Thanks Sal.
Weird flex but ok

I love this Channel...so helpful😍
first on khan ACADEMY!!!
can you please make videos about Geography?

The last two sentences to this video are so profound, could you please do a video on that?? Thank you
I'm love khan videos! Very big learning and still funny videos

Amazing!! Thank you :)
Thanks from south sudan
Why would water be a bent molecule as opposed to a line, due to how the charges like to repel similar charges?
Very interesting.
Hey khan what is hydrogen made off?

اريد خان اكادمي بالعربية انا و الشعب العربي i want khan acadmy by arabic languages
google pays people to transpose videos Im pretty sure... just get a 50$ mic do it your self
So, the high heat capacity means that water is very resistant to changing its temperature, eh?

8:43-8:51 did Khan Academy just endorse nihilism?
From which section is this? Biology?
I think inorganic chemistry
Biochemistry
-AP/College Biology
-Biology library
no!!! i'm second one!!!
the fact that he bonded all of them but one makes me so mad
3 ed
makes me thirty now,I need a beer...
This made me twenty-eight
