WebJan 30, 2024 · ΔH = ΔU + ΔPV. If temperature and pressure remain constant through the process and the work is limited to pressure-volume work, then the enthalpy change is given by the equation: ΔH = ΔU + PΔV. Also at constant pressure the heat flow ( q) for the process is equal to the change in enthalpy defined by the equation: ΔH = q. prince george\u0027s county school board members https://tywrites.com
