Hi
Can somebody please help. I have an assignment question and I don't even know how to start.
The question reads as follows:

The constant-pressure heat capacity of a perfect gas was found to vary with temperature according to the expression Cp(J/K) = 20.17 + 0.4001(T/K). Calculate q, w, delta U and delta H when the temperature is raised from 0 degrees celsius to 100 degrees celsius :

(a) at constant pressure
(b) at constant volume

I will appreciate ANY help.
Thanx

Do you know the definition of C_p in terms of derivatives of thermodynamic potentials?  That's a good place to start.
