# Heat Capacity at Constant Volume

At a constant volume, abbreviated as \(C_v\), all the heat added goes into raising the temperature. The value of heat capacity depends on whether the heat is added at constant volume, constant pressure, etc.

### Heat Capacity at Constant Volume Formula

\(\large{ Q = n \; C_v \; \Delta T }\)

Where:

\(\large{ Q }\) = heat transfer

\(\large{ n }\) = amount of substance

\(\large{ C_v }\) = heat constant volume

\(\large{ \Delta T }\) = temperature differential
