One mole of an ideal gas is kept enclosed under a light piston
(area=[IMAGE] ) connected by acompressed spring (spring
constant 100 N / m). The volume of gas is [IMAGE] and
its temperature is 100K. The gas is heated so that it compresses the
spring further by 0.1 m. Then the work done by the gas in the process
is: (in Joule) (Take R =8.3 J / K -mole and suppose there is no
atmosphere).,d 100 N / m½

Show answer and solution▾

Before heating let the pressure of gas be
[IMAGE] from the equilibrium piston.
