Vedclass · Answer

(C) For an adiabatic process,the heat exchange $Q = 0$.According to the first law of thermodynamics,$Q = \Delta U + W$. Since $Q = 0$,we have $W = -\Delta U$. This means the work done is equal to the negative change in internal energy,or $|W| = |\Delta U|$. Thus,statement $(B)$ is correct.For an ideal gas,the internal energy change is $\Delta U = nC_v \Delta T$. Therefore,the work done $W = -nC_v(T_2 - T_1) = nC_v(T_1 - T_2)$. The magnitude of work done is proportional to $(T_2 - T_1)$. Thus,statement $(E)$ is correct.Statements $(A), (C),$ and $(D)$ are incorrect because they describe isothermal or other processes,not adiabatic processes.Therefore,the correct option is $(B), (E)$ only.
