A Container having 1 mole of a gas at a temperature `27^(@)` has a movable piston which maintains at constant pressure in container of 1 atm . The gas is compressed until temperature becomes `127^(@)`. The work done is ( C for gas is 7.03 cal / mol – K )

A

703 J

B

831 J

C

121 J

D

2035 J

Text Solution

Verified by Experts

The correct Answer is:
B
At P = constant
`W = PDeltaV=n R DeltaT`
`=1xx8.31xx100=831J`.
