JEE Main2012PhysicsThermodynamicsActual
The pressure of an ideal gas varies with volume as P= V , where is a constant. One mole of the gas is allowed to undergo expansion such that its volume becomes ' m ' times its initial volume. The work done by the gas in the process is
Options
- AV 2 (m^2-1 )
- B^2 V^2 2 (m^2-1 )
- C2 (m^2-1 )
- DV^2 2 (m^2-1 )
Correct answer
D. V^2 2 (m^2-1 )
Step-by-step solution
Given P= V Work done, w= _V^ m V P d V= _V^ m V V d V= V^2 2 (m^2-1 ) .
