When do we use the 3/2R or 5/2R in place of Cvm/Cpm? And when refering to mono, linear, or non-linear what exactly is that talking about. Thanks in advance.

3/2R and 5/2R are used for monoatomic or diatomic gases like N(g) or O2(g)

they are typically used when using the 2 of the 3 different forms of the entropy equation:

1. Constant volume (isochoric): dS = n*Cv*ln(T2/T1)

2. Constant pressure (isobaric): dS = n*Cp*ln(T2/T1)

We use those if we are talking about monoatomic ideal gases. Dr. Lavelle said that we would not be tested on diatomic or linear gases.
