- The molar specific heat capacity of a gas at constant volume is defined as the amount of heat required to raise the temperature of 1 mol of the gas by 1 °C at the constant volume.
\({C_v} = {\left( {\frac{{\Delta Q}}{{n\Delta T}}} \right)_{constant\;volume}}\)Additional Information
- The molar specific heat of a gas at constant pressure is defined as the amount of heat required to raise the temperature of 1 mol of the gas by 1 °C at the constant pressure.
\({C_p} = {\left( {\frac{{\Delta Q}}{{n\Delta T}}} \right)_{constant\;pressure}}\)
- The relation between the ratio of Cp and Cv with a degree of freedom is given by
\(\gamma = \frac{{{C_p}}}{{{C_v}}} = 1 + \frac{2}{f}\)
Where f = degree of freedom
For monoatomic gas f = 3
For Diatomic gas f = 5
