Chemistry - Thermodynamics - I Question with Solution | TestHub

The work done on the gas is maximum when it is compressed irreversibly from ($p_2 , V_2)$to$(p_1 , V_1)$against constant pressure$p_1$

If the expansion is carried out freely, it is simultaneously both isothermal as well as adiabatic

The work done on the gas is less when it is expanded reversibly from$V_1 to V_2$under adiabatic conditions as compared to that when expanded reversibly from$V_1 to V_2$under isothermal conditions.

The change in internal energy of the gas (i) zero, if it is expanded reversibly with$T_1= T_2$, and (ii) positive, if it is expanded reversibly under adiabatic conditions with$T_1 \ne T_2$
