So the more of the system that we have, the largest system, the more enthalpy we have. And that's because enthalpy is related to internal energy, and internal energy is related to number of moles, number of particles. So the more particles we have, the more enthalpy we have. And that's why it's an external property. So because enthalpy is a man made concept, we can't talk about absolute values of enthalpy. They simply do not exist.
