An electrical heater delivers 4.070 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 = 2.442 kJ. What is the change in internal energy for the system?

dE = q + w
q = +4070 J
w = -2442 J
dE = ?
q = +4070 J
w = -2442 J
dE = ?
