When the state of a gas adiabatically changed from an equilibrium state A to another equilibrium state B, an amount of work done on the system is 35 J. If the gas is taken from state A to B via process in which the net heat absorbed by the system is 12 cal, then the net work done by the system is (1 cal = 4.19 J)
