## monoatomic vs diatomic C constants?

Volume: $\Delta S = nR\ln \frac{V_{2}}{V_{1}}$
Temperature: $\Delta S = nC\ln \frac{T_{2}}{T_{1}}$

### monoatomic vs diatomic C constants?

the constants and equations sheet doesn't actually give the Cv or Cp of diatomic gas molecules, only calling the monoatomics "ideal gases" - will he differentiate/expect us to use the diatomic values at all during the test?

I think we only need to know the constants for a monoatomic gas b and if a question has a diatomic gas, the required constants will be given to us in the problem.
