Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
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. Forever. #YouCanLearnAnything

This is the best it covers work done by the gas and also first law of thermodynamics and also tells about the heat capacity it covers all the thermodynamics in just video really apreciate it
Fell asleep in just about every class this week, thanks Khan for teaching me
It was a brilliant explanation. I enjoyed a lot. Thank you.
And the student might ask at 1:42 'if we raise the pressure we make the volume smaller', how can we be so sure that K becomes greater since the initial state?
Georgios Papadopoulos because they are directly proportional
if you increase pressure the temperature of the gas will also increase....
I don't leave comments much, but this video was the best explanation of chemistry in general! Thank you thank you
awesome explaination
The best explanation I’ve ever found! I really appreciate it. Thank you
Great work David! Thank you!
Brilliant. Was lost until this came.
Sir you literally derived the formulaes without with using diffrentiatal calculas truly a legend
Love how well these videos align with the MCAT objectives.
This is really helpful. Thank you so much.
한국 사람?! ㅋㅋ
Thanks lot. Before see this I wasted 1hour of time in searching google. Lots f love to Khan academy 💓💓
Another great video tutorial on physics that I found very easy to apply in chemistry, thank you so much
Thanks now I am understand that 😀
Loved it, explained so nicely. Thank you
helped....thank u
Thankyou!
THANK YOU SO MUCH
Wow.
Thank you it really helps me out
great video as always
why will all dT's get cancelled out at 10:54?
It's basic math (p+q)/s = p/s + q/s
Salute ❤
wow. Teaching is an art
Excellent 👏
THANK YOU SO MUCH 💜
Nice explanation
I wish you to answer my question .. what is the type of program board that you used to explain that video ??
It's an ok video. But, Khan is huge and so it also has a huge responsibility. Here, the same symbols are used for molar heat capacity and "regular" heat capacity. Specific heat capacities, molar heat capacities, and any other variables need to be distinguished, probably here with different subscripts. I strongly suggest you re-do the video or at least add annotation overlays to use different symbols for different variables. To use the same symbol is really to propagate confusion within the physics and chemistry communities. If anyone else is reading this and they comprehend what I am saying please upvote my comment to help bring awareness.
By the way, Wikipedia is also struggling with this issue and that's the other place I can think of where we can all work together to help fix this sort of problem.
from where we got the 3/2 of the first equation ?
😮it says how much heat is required in joules to increase temprature of system by 1 unit
3/2 KT
How was it derived
Best
10:55 how exactly do all the delta Ts go away? You have (dT+dT)/dT
Which is 2dT/dT
Which is dT
How can dT completely nullify 2dT? 🤔
Im being condescending but, this is an actual stakes question, I've got exams in 3 days, so... pls reply - quick! 🙏🏽
just the two above(numerator) terms by ∆T.its simple maths . What you are thinking is completely wrong brother
You need to review your basic algebra, my dude. 2(deltaT)/delta T is just 2.
Confused at 7.40...du=w+q????
It's not dU, it's delta U. dU is the differential of U, not the same.
Internal energy (U) is a state function, meaning it tells you how much internal energy is in the system at that state. q and w are path functions, meaning they tell you how much heat or work was added/removed. You can't say "this glass of water has this much work in it", you can only say how much work was done on it or removed. However much heat and/or work was added/removed is how much the internal energy was changed.
Am totally lost on this topic
king
bellisimo
confused af.
salman khan is better than this !
NOO! You're the stupid here
yes we want sal khan back plz
