Vedclass · Answer

(A) In an isothermal process,the temperature of the system remains constant,so $\Delta T = 0$. Since the internal energy of an ideal gas depends only on its temperature $(U = f(T))$,the change in internal energy $\Delta U$ is zero. According to the first law of thermodynamics,$\Delta Q = \Delta U + \Delta W$. Substituting $\Delta U = 0$,we get $\Delta Q = \Delta W$. This means that all the heat supplied to the gas is used to perform external work.
