Vedclass · Answer

(B) The correct option is $(b)$.Mayer's relation,$C_p - C_V = R$,is derived based on the equation of state for an ideal gas $(PV = nRT)$.This relation holds true for any ideal gas,regardless of its atomicity (monoatomic,diatomic,or polyatomic).For real gases,the relation is given by $C_p - C_V = TV \beta^2 / K_T$,where $K_T$ is the isothermal compressibility and $\beta$ is the isobaric thermal expansion coefficient. Since real gases do not follow the ideal gas law exactly,this specific relation $C_p - C_V = R$ is only strictly valid for ideal gases.

The relation $C_p - C_V = R$ ($C_p$ and $C_V$ are the molar specific heats at constant pressure and volume) is exactly true for
