Difference between Heat and Enthalpy

What is the difference between heat and enthalpy? Can they just be used interchangeably?

Enthalpy is specifically the amount of heat absorbed or released by a certain compound during a reaction.

Heat is a transfer of energy due to a temperature difference. Enthalpy is the change in amount of heat in a system at constant pressure. You can only use heat and enthalpy interchangeably if there is no work being done to the system.
