enthalpy vs heat

[Ishita Monga 1B]

is there a difference between enthalpy and heat?

[Naomi Jennings 2H]

Yes, because enthalpy is a state function and heat is a path function. The enthalpy value will be determined by the current state of the substance, whereas heat is defined by the textbook as "the energy that is transferred as a result of a temperature difference between a system and its surroundings". Pretty much, heat is discussing energy that is moving from substance a to substance b, but enthalpy is talking about the energy of substance a or of substance b.
However, they're pretty similar when talking about the change in enthalpy between substance a to b, because that energy is released or absorbed as heat.

I think the most simple way to think of it is that enthalpy is determined by the amount of heat released or absorbed, rather than by the substance heat itself.
