What is the relationship between state property and enthalpy?

Enthalpy is a state property, meaning that it is a value that does not depend on the path taken to achieve a certain value, only that value in a certain instant.

For example, think of a mountain and an object. An object will be a certain height up the mountain regardless of how that height was achieved (i.e, did the object come down from a higher altitude or start at the bottom?). Height is a state property. If you were to take into account the path taken by the object to achieve such a height, then it would no longer be a state property.

A state property is a value that does not depend on the path you take to get to a state, as long as you get to the final state. Enthalpy is a state property because this value only cares about the final and initial properties.

Enthalpy is a state function because it depends only on two thermodynamic properties such as temperature and pressure, or temperature and entropy, or any pair of other state functions. Not on the process it took to get there

A state property is something (a quantity) that is independent of the path taken to reach a specific value or endpoint. Enthalpy is the total heat of a system and is also a state property.

A state property is one which is additive such as enthalpy or free energy. So, enthalpy relates to state functions as it is one as shown by Hess' Law.
