The change in specific entropy of a system undergoing a reversible process is given by \({S_2} - {S_1} = (C_P - C_V) ln(\frac {V_2 }{V_1}) \). This is valid for which one of the following?
1
Adiabatic process undergone by an ideal gas
2
Isothermal process undergone by an ideal gas
3
Polytropic process undergone by a real gas
4
Isobaric phase change from liquid to vapour
