Thermodynamics vs Enthalpy

Postby Jessica Helfond 2F » Wed Jan 30, 2019 8:29 pm

How is thermodynamics different from enthalpy? I get that thermodynamics is heat transfer, but how does that differ from enthalpy, which is the heat absorbed or released?

Enthalpy is a thermodynamical change. The difference is that enthalpy is in relation to a set point therefore it is expressed as the change in heat whereas thermodynamics is just the overarching term for transfer of heat in science. Enthalpy is the heat of a system and delta H is the change in this value with respect to the original enthalpy of the equation.

Thermodynamics is the branch of physical science that deals with the relations between heat and other forms of energy. Enthalpy is a thermodynamic quality that means the total heat content of a system and is equal to the internal energy of the system plus the product of pressure and volume.
