The workdone on the system in changing the state of a gas adiabatically from equilibrium state A to equilibrium state B is 32.4 J. If the gas is taken from state A to B through another process in which the net heat absorbed by the system is 13.5 cal. then the net workdone by the system in the later case is
(1 cal = 4.2 J)
