JEE Main 29 June 2022, Shift 2, Physics Q38

Question 38 of 90 in this shift, Physics question 8 of 30, Section A.

Starting with the same initial conditions, an ideal gas expands from volume

V_1

V_2

in three different ways. The work done by the gas is

W_1

if the process is purely isothermal,

W_2

, if the process is purely adiabatic and

W_3

if the process is purely isobaric. Then, choose the correct option

(1) $W_1<W_2<W_3$
(2) $W_2<W_3<W_1$
(3) $W_3<W_1<W_2$
(4) $W_2<W_1<W_3$ Official answer
