### Using Cv and Cp

When calculating entropy do we always use Cv for constant volume and Cp for constant pressure?

Yes, but most of the time I believe the question will refer to Cv

Cv is for constant volume and Cp is for constant pressure, yes.

### Re: Using Cv and Cp

Constant volume uses Cv and Constant pressure uses Cp. Cv is normally used though.

### Re: Using Cv and Cp

How do we know when to use Cv, and when to use Cp?
