Practice Midterm 3A

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

Practice Midterm 3A

How do we know to whether to use Cv or Cp when calculating with the nClnT2/T1 equation?

Use Cv when the volume is constant and Cp when the pressure is constant.

Cv with constant volume and Cp with constant pressure.

Also, take in mind that if T is increasing, there will be a change in P or V to make up for it, given that PV = nRT.
