One mole of an ideal gas is kept enclosed under a light piston (area = 10^(-2)m^(2)) connected by a compresses spring (spring constant 100N//m) . The volume of gas is 0.83 m^(3) and its temperature is 100K . The gas is heated so that it compresses the spring further by 0.1 m . The work done by the gas in the process is N xx 10^(-1)J . Find N . (Take R = 8.3 J//K-"mole") and suppose there is no atmosphere).
