The following figure shows a system and its environment. In figure a, the system gains 1500 J of heat from its surroundings and 2200 J of work is done by the system in the environment. In part b, the system gains 1500 J of heat, but 2200 J of work is done in the system by the environment. For each case, determine the change in internal energy.
