Starting with the same initial condition...

Starting with the same initial conditions, an ideal gas expands from volume `V_1` to `V_2` in three different ways, the work done by the gas is `W_1` if the process is purely isothermal, `W_2` if purely isobaric and `W_3` if purely adiabatic, then

A

`W_(2)gtW_(1)gtW_(3)`

B

`W_(2)gtW_(3)gtW_(1)`

C

`W_(1)gtW_(2)gtW_(3)`

D

`W_(1)gtW_(3)gtW_(2)`

Text Solution

Verified by Experts

The correct Answer is:
a

It is clear from the graph that on the basis of area under p-V curve for different processes `W_(2)gtW_(1)gtW_(3)`.
