Universal relation between Isobaric molar heat capacity (cP) and Isochoric molar heat capacity (cV):
| LaTeX Math Block | ||||
|---|---|---|---|---|
| ||||
c_P = \frac{C}{\nu}- c_V = \frac{1}{\nu} \cdotV_m \, T \, \frac{\delta Qalpha_V^2}{\delta beta_T} |
where
| temperature |
| molar volume | ||||||||
|
| isothermal compressibility |
|
| thermal expansion coefficient |
For the ideal gas it will take a form:
| LaTeX Math Block | ||||
|---|---|---|---|---|
