# Specific Heat Capacity at Constant Pressure

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
