Which of the following statements/relationships is not correct in thermodynamic changes ?
(a) \( \Delta \mathrm{U}=0 \) (isothermal reversible expansion of a gas)
(b) \( \mathrm{w}=-\mathrm{nRT} \ln \frac{\mathrm{V}_{2}}{\mathrm{~V}_{1}} \) (isothermal reversible expansion of an ideal gas)
(c) \( \mathrm{w}=\mathrm{nRT} \ln \frac{\mathrm{V}_{2}}{\mathrm{~V}_{1}} \) (isothermal reversible expansion of an ideal gas)
(d) For a system of constant volume heat involved directly changes to internal energy.
\( \mathrm{P} \)
