1. An ideal gas is expanded from (p 1 , V 1 , T 1 ) to (p 2 , V 2 , T 2 ) under different conditions. The correct statement(s) among the following is(are)

Options

A : 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

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

C : The work done by 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

D : The change in internal energy of the gas is (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 ¹ T 2
