Heat Content or Enthalpy

Enthalpy is a thermodynamic quantity equivalent to the total heat content of a system. Thermodynamics means the flow of heat energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More. It is a branch of physics that deals with the relationship between heat and other forms of energy. Enthalpy changes are heat changes accompanying physical and chemical changes.

The symbol of heat change or enthalpy change is ∆H, where ∆ stands for change and H stands for heat.
