I was "taught" this 5 times by now, only only just now do I understand where W = PΔV comes from. Thanks!

[dorothyyam]

wow, this is the best explanation I've come across... Amazing!!

[averageredditor]

omggg this lecture was so easy to understand,

p.s if you are a student from Pakistan please do watch this video this is a 1000 times better than the books and the conventional techer lecture on this topic.

[ChiChi-ulbe]

Was the point of this video to see where the equations are derived from? I'm a little confused about how we would use this and apply it on the mcat exam

[karolinagadek]

It's incredible how good you are at explaining. I'm covering this topic rn during bsc and I couldn't understand a thing until I saw this video.

[jonathantannous]

thks soo much I'm glad I came across this clarifying video

[williamnelson]

Best explanation I have ever seen. You have a "friction free" way of sharing your thermodynamic insights! Many thanks.

[clowie]

its a good video, khan always have good

[spanionneo]

Amazing. Drove the ball home for me. Thank you!

[potcharawongyai]

this is the best video about cp and cv thanks!

[mohammedasaad]

your explanation is better than my professor's....

[zeustheboerboel]

Thanks sir! You made it way way easier.

[bobnob]

thank you good sir, great video and had everything i needed in it

Why Pressure is kept cOnstant while studying heat capacity at cOnstant vOlume?

[badiruayebare]

i want to help me with this calculation, "calculate the two principle molar heat capacities of oxygen if their ratio is 1.4, density of oxygen at stp is 1.43kg/m^-3, 1atm=1.01*10^5 Pa and molar mass of oxygen is 32.0*10^-3kg/mol?"

[taradhipa]

Well explained, really nice!!!!   Keep it up

[kaibutsusennin]

What if it's in constant volume, but you have like some sort of Turbine inside the closed system that's putting work

[shujaathussain]

Thank you KHAN, but there is no sound, its better to have.
