Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful. About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content. For free. For everyone.

Lol. Reverse sublimation that's so hilarious
-
12:11 It is Deposition
-
deposition is inverse sublimation :)
-
This was so helpful. Thank you.
-
Didn't they have that blue ice stuff for keeping coolers cool? That was frozen CO2, right?
-
A lot of chemists just use the word sublimation rather than deposition, and you can just understand weather it means going from solid to gas or from gas to solid from the context.
-
Good video! The word is deposition hahah
-
thanks for such a good video. that helped me to understand very well.
-
whats is his favorite color?
-
Awesome video! I believe deposition is reverse sublimation.
-
Can you, you, you, please, please repeat yourself? Repeat yourself?
-
If anyone is watching through the videos, could they please reply to this comment all of the annotations/mistakes that Sal made (up to Van Der Waals Forces, video 30)?
By this, I mean all the bubbles that popped up when he corrected himself.
I'm afraid I missed some since I watched mostly on my phone, and I don't want to have learned wrong information.
Thank you! -
I wish Sal was my teacher in all science subjects ever
-
thanks so much this helped me so much for my science competition
-
Great video. Thanks!
-
Thank u so much, excellent helpful video
-
Excellent video, as usual, but I am assuming that Sal had too much in his brain at the end of the video to remember that deposition is the opposite of sublimation? He mentioned condensation, while he was trying to remember, which is molecules going from a gas to a liquid; but, going from a gas to a solid is deposition (e.g., water vapor on a cold window forming ice crystals). The opposite, of which, is sublimation: going from a solid to a gas (e.g., "dry ice").

anything you don't know?

I'd like to point out that water is a peculiar fluid. Normally, the melting point of a substance would increase when pressure increases. This is due to water ice's special structure. But still, great video!

This makes no sense
