Question

Starting with the same initial conditions, an ideal gas expands from volume V1 to V2 in three different ways. The work done by the gas is W1 if the process is isothermal, W2 if isobaric and W3 if adiabatic, then :

Options

A.W2 > W1 > W3
B.W2 > W3 > W1
C.W1 > W2 > W3
D.W1 > W3 > W2 

Solution

As W.D. is isobaric > W.D. in Isothermal > W.D in adiabatic
or  W2 > W1 > W3
Hence option (A) is correct.
