Question

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

Accepted Answer

The corresponding p-V graphs (also called indicator diagram) in three different process will be as shown :
Area under the graph gives the work done by the gas
(Area)₂ > (Area)₁ > (Area)₃
∴ W₂ > W₁ > W₃
