Using Cv and Cp

Postby JesseAuLec1Dis1G » Mon Feb 10, 2020 1:13 pm

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.

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

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