FREE Expert Solution

We are being asked to calculate ΔE or the internal energy of the system. The internal energy (ΔE or ΔU) of a system can be calculated from the heat and work of the system. The relationship between internal energy, heat, and work is shown in the following equation:


E = q +w

ΔE = internal energy, J
q = heat, J
w = work, J
