The change in the internal energy of the gas in the cylinder is 763 J
From the first law of thermodynamics, the change in internal energy(U) of a system is equivalent to the difference between net heat transfer(Q) into the system and the net work done(W) on the system
The equation for the change in the internal energy from the first law of thermodynamics is:
ΔU = ΔQ - ΔW
ΔU = 875 J - 112 J
ΔU = 763 J
