As I understand it, internal energy is equal to work + heat in the equation ∆U = q + w. However, there's a second equation that reads ∆U = ∆H - P∆V. Change in heat represents q, and P∆V = work of expansion. What is the reasoning behind the positive sign in ∆U = q + w changing to a negative in ∆U = ∆H - P∆V?
