heat δq and work δw done on or by the system, δu = δq + δw and for a reversible process, the heat energy change δq = tδs and the work done δw = -pδv ; (for non-spontaneous reactions , see the discussion at [ ]). therefore, δu = tδs - pδv thermodynamics introduces a term h that is the enthalpy; a measure...
