As we learnt in 

First law in isobaric process -

\Delta U= n\, C_{v}\Delta T

= n\frac{R}{\gamma -1}\Delta T
 

- wherein

\Delta Q= \Delta U+W

         = n\frac{\gamma \: R}{\gamma -1}\cdot \Delta T

\Delta Q= nC_{p}\: \Delta T

 

 C_v=\frac{\Delta V}{n\Delta T}=\frac{\Delta Q_v}{n\Delta T}\Rightarrow S=\frac{\Delta Qv}{m\Delta T}

C_v is defined as amount of heat required to raise temperature of the unit mass through one degree.
