    The enthalpy is defined by H = E + pV for a change in the states of system ΔH = Δ (E + pV) = ΔE + Δ (pV) = ΔE + pΔV + VΔp    ....(i) 1st law of thermodynamics states that ΔE = q + W = q - pΔV    ....(ii) From equations (i) and (ii) ΔH = q - pΔV + pΔV + VΔp = q + VΔp When the pressure is constant, Δp = 0, and thus VΔp = 0, therefore ΔH = q (at constant pressure) or, ΔH = qPRead more on Sarthaks.com - https://www.sarthaks.com/602390/with-the-help-of-first-law-of-thermodynamics-and-the-definition-h-e-pv-prove-that-h-qp
