# Specific Heat Capacity at Constant Pressure

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Specific heat ratio, abbreviated as $$C_p$$, is the ratio of two specific heats.  If we specify any two properties of the system, then the state of the system is fully specific.

## Specific Heat Capacity at Constant Pressure Formula

 $$\large{ C_p = \left(\frac{ \partial H }{ \partial T }\right)_p }$$

### Where:

$$\large{ C_p }$$ = heat constant pressure

$$\large{ \partial H }$$ = enthalpy rate of change

$$\large{ p }$$ = pressure

$$\large{ \partial T }$$ = temperature rate of change

$$\large{ \partial }$$ = designates heat as a path function
