Heat and Ethalpy

[Mary Becerra 2D]

What is the difference between heat and enthalpy? From my understanding, enthalpy is the measurement of the change of heat after a reaction. Is this correct, wrong, or correct but too simplistic?

[John Huang 1G]

In thermodynamics, heat is the energy transferred as a result of temperature differences.

Enthalpy is the amount of heat released or absorbed at a constant pressure. Enthaply has to be measured at a constant pressure. If heat was being transferred under conditions of varying pressures, then we would not consider it enthalpy.

Hopefully this clears up your confusion.

I think that heat is the energy transferred in thermal reactions while enthalpy is the total energy in a thermodynamic system.

In addition:
Heat is defined as q, which more specifically means the quantity of heat.
While Enthalpy is defined as H or delta H
