HW 9.13 Cp vs Cv

In 9.13, why is Cv used instead of Cp when finding the change in entropy resulting from the increase in temperature? Cv is the heat capacity at constant volume, and volume in this question isn't constant

Could you please clarify? I'm looking at the problem itself, and Cp nor Cv are used.

In the solution manual errors PDF, the equation ∆S=nCvln(T2/T1) is used, with Cv being 5/2 R
