Vedclass · Answer

(B) For an ideal gas,the internal energy $U$ is a function of temperature $T$ only,i.e.,$U = f(T)$.In an isothermal process,the temperature of the system remains constant $(dT = 0)$.Since the internal energy depends only on temperature,if the temperature does not change,the internal energy cannot change.Therefore,the change in internal energy $\Delta U$ for an ideal gas in an isothermal process is always zero $(\Delta U = 0)$.Thus,the answer is no.

Can the change in internal energy of an ideal gas be non-zero during an isothermal process?
