Reference no: EM13325716

An electrical heater delivers 7.880 kJ of energy (as heat) to a system consisting of the gas inside a cylinder having a movable piston. As a result, the piston moves against a constant external pressure such that P ?V = 2.364 kJ. What is the change in internal energy for the system? Answer to the nearest 0.001 kJ.
