The internal energy of a system changes becasue the system gains 176 J of heat and performs 312 J of work. In returning to its initial state, the system loses 104 J of heat. During this return process, what work is involved? If the work is done by the system, then give the work involved as a positive number. If the work is done on the system, then give the work involved as a negative number.
