Re: Heat v Enthalpy
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.

Re: Heat v Enthalpy
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.
Re: Heat v Enthalpy
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.
