When the state of a gas is adiabatically changed from an equilibrium state A to another equilibrium state B, the amount of work done on the system is 35 J. If the gas is taken from state A to B via a process in which the net heat absorbed by the system is 12 cal, the net work done by the system in _______ (1cal=4.2J)
