An insulated cylinder contains nitrogen ...


An insulated cylinder contains nitrogen gas which is sealed on the top by a heavy metal piston of mass m. piston is free to move with negligible friction, initial height of the piston is 0.3 m at temperature `27^(@)C` when it is givenn some heat with the help of an electrical circuit piston slowly rises to height 0.5 m above the bottom of the cylinder. During expansion of te gas, net heat absorbed by the nitrogen gas:

A

Equal to work done by nitrogen gas on the piston

B

Greater to work done by nitrogen gas on the piston.

C

Less to work done by nitrogen gas on the piston

D

Will be always twice of the work done by the gas on the piston.
