Homework Statement
Suppose that 31.4 J of heat is added to an ideal gas. The gas expands at a constant
pressure of 1.40x104 Pa while changing its volume from 3.00x104 to 8.00x104 m3.
The gas is not monatomic, so the relation CP = 5/2R does not apply. (a) Determine the
change in the internal energy of the gas. (b) Calculate its molar specic heat capacity
CP .
Homework Equations
The Attempt at a Solution
I have completed part a) using the knowledge that it is an isobaric process, but I'm a bit unsure of my answer for b)
My textbook says that for a diatomic ideal gas, Cp is given by 7/2 R, but the question only says the gas is not monatomic.
Is there a piece of info I'm missing?
Thanks!
