With same initial conditions , an ideal ...

With 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 isothermal , `W_(2)` if isobaric and `W_(3)` if 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
Here for isobaric process , work done is largest , next for isothermal and then for adiabatic process,
`W_(2)gtW_(1)gtW_(3)`
