Answer 2

enthalpy is a thermodynamic quantity equivalent to the total heat content of a system, equal to the internal energy of the system. while entrpy is a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work. vapour pressure is the pressure of a vapour (evaporation) in contact with its liquid or solid form.
