Thermodynamics - 4-4 Calculating U (internal energy) and H (enthalpy) using specific heats

[@lotusbackground7220]

I really appreciate the fact that you make your knowledge freely accessible. Thank you so much Professor.

i got an A in thermo ..im here to say thank you . YOU ARE THE BEST :-)

[@engineeringdeciphered]

Awesome!! Way to go!!

[@joyia.1]

My teacher didn't teach me how to use the tables. He just gave the lecture and that's it. But you are amazing sir.

mine is too

[@walidwilliams2553]

You're literally the best! everyone going through thermo definitely needs to watch your series.

thank you it´s very helpful ❤

[@nicolascaleroarteaga4461]

Some teachers should just play your videos in class and have sit🤗

Professor I have a confusion about sth here.When I calculate(at constant specific heat values) delta u by finding _u2_ and _u1_ values and subtracting them compared to _cv*(aT2-T1)_? I wonder why it is like that? I really appreciate your help

Thank you so much!

Sir, is table A-2(a) valid for UPTO 300 K (i.e. T= 0-300 K) or is valid only if the gas is AT a temperature of 300 K (i.e. T=300 K)

[@engineeringdeciphered]

I think it’s just at 300K. Table b and c are for more temperatures. And then the next tables are for liquids.

What is Cp bar?

[@engineeringdeciphered]

I think that would be the Cp per molar mass. Look at the units of it: probably has kmol in there. You would need to multiple that by the molar mass of the substance to get it to per mass.

@@engineeringdeciphered You mean "divide".
