A gas is expanded from volume `V_(0) = 2V_(0)` under three different processes. Process `1` is isobaric process, process `2` is isothermal and process `3` is adiabatic. Let `DeltaU_(1), DeltaU_(2) and DeltaU_(3)` be the change in internal energy of the gas in these three processes. then

Options

A. `Delta U_(1) gt Delta U_(2) gt Delta U_(3)`
B. `Delta U_(1) lt Delta U_(2) lt Delta U_(3)`
C. `Delta U_(2) lt Delta U_(1) lt Delta U_(3)`
D. `Delta U_(2) lt Delta U_(3) lt Delta U_(1)`

Answer

A

Explanation

a. Change in temperature in process 1 will be greater and in process 3 will be least.
