Entropy Equation Specific Heat Capacity

Postby Shuyi Yu 1B » Sat Feb 02, 2019 9:08 pm

How do you know when to use 3/2 R instead of the specific heat capacity provided on the cover sheet?

If you are referring to the (3/2)R constant for the ideal gas, Cv, you would use that when volume is constant.

You will know to use this based on whether you are dealing with ideal gas conditions and based on what kind of information you are given relating to heat capacity.

The information given in terms of constant volume or constant pressure should also help determine what you need.
