A certain ideal gas has a molar specific heat at constant volume 7R/2.What is its molar specific heat at constant pressure?
A)5R/2
B)3R/2
C)8R
D)9R/2
E)6R

Question

The relationship between the molar specific heat at constant volume and constant pressure for an ideal gas is given by:
Cp - Cv = R
Where Cp is the molar specific heat at constant pressure, Cv is the molar specific heat at constant volume, and R is the gas constant.
Substituting Cv = 7R/2, we get:
Cp - 7R/2 = R
Solving for Cp, we get:
Cp = 9R/2
