Heat capacity
« on: April 30, 2015, 12:28:04 PM »
I need to calculate the change in internal energy for 2.0 mol of an ideal gas from 27C in 1 atm to 344C in 17 atm.
Heat capacity:
Cp=20.9+0.042T*J/(K*mol)

(cp-cv=nR does not apply to this situation)

I tried doing an intergral on Cp to get the change in enthalpy but it isnt coming out to the right answer.
any help would be much appreciated!

Why not share, to help others that may pass this way in the future?
