"WebIn terms of pronunciation, the first syllable of entropy is commonly stressed, whereas the later syllable of enthalpy is generally emphasised. Enthalpy(H) is the sum of the internal energy(U) and the product of pressure(P) and volume(V). Enthalpy H can be written as, H = U + pV. Where, H = Enthalpy of the system. U = Internal energy of the system " - Enthalpy or entropy
