### Heat v Enthalpy

Why is heat not a state function while enthalpy is?

Heat depends on the path taken to obtain the current state. Enthalpy is a state function because it only depends on the initial and final values of heat, so it doesn't depend on the path taken.

Enthalpy is a state function that keeps tract of the losses of energy during heat transfer. Heat itself, however, like work, is not a state function because it depends on the path used to go from the initial to the final state.

What helps me is to look at the formula of heat and enthalpy. Enthalpy can be calculated using the initial and finals states. Heat is calculated using a bunch of parameters meaning it depends on the path taken.
