The enthalpy of the system remains constant.

Vedclass · Answer

(B) An isothermal process is defined as a process in which the temperature of the system remains constant $(dT = 0)$.For an ideal gas,the internal energy $(U)$ is a function of temperature only $(U = f(T))$. Therefore,if the temperature is constant,the internal energy remains constant $(dU = 0)$.However,for real gases or condensed phases,enthalpy $(H = U + PV)$ depends on pressure as well. Even if temperature is constant,enthalpy may change if the pressure changes.Thus,the statement that the enthalpy of the system remains constant is not universally true for all isothermal processes,making it the false statement.

Identify the false statement regarding an isothermal process from the following.
