Re: Internal Energy, U
delta u is only equal to delta h when pressure is constant and volume doesn't change

Re: Internal Energy, U
A counter example would be in an isolated system, where neither heat nor matter can be exchanged, dU = q + w.

Re: Internal Energy, U
ΔH = ΔU + PΔV
ΔU is only equal to ΔH when the pressure is constant and the change in volume ΔV = 0.
ΔU is only equal to ΔH when the pressure is constant and the change in volume ΔV = 0.
