In thermodynamics, "enthalpy} is the sum of the internal energy $$U$$ and the product of pressure $$p$$ and volume $$V$$ of a system. The characteristic function (also known as thermodynamic potential) \textit{enthalpy} used to be called \textit{heat contents}, which is why it is conventionally indicated by $$H$$. The specific enthalpy of a working mass is a property of that mass used in thermodynamics, defined as $$h=u+p \cdot v$$, where $$u$$ is the specific internal energy, $$p$$ is the pressure, and $$v$$ is specific volume. In other words, $$h = H / m$$ where $$m$$ is the mass of the system. The SI unit for \textit{Specific Enthalpy} is \textit{joules per kilogram".
