What does the term "state function" entail? All I've seem to understand from it is that it's only dependent of its current calculated state and that you can add it's values. Other than that, what does "state function" mean?

A state function means that only the initial state and final state are needed to determine the value. I think Lavelle's example of how only the initial and final destinations matter when you hike a mountain and how the pathway you took is irrelevant explains conceptually what a state function is.

The value of state functions are independent of pathways taken to reach their initial/final values. Since pathway becomes inconsequential, the quantity is only dependent on initial and final values.

Examples of state functions include density, internal energy, enthalpy, and entropy.

A state function relies on initial and final values, not the pathway taken.

The value of a state function is only dependent on the initial value and the final value.

State functions are independent values regardless of the pathway to get to the final value. The quantity only matters based on the final and initial values, and not the pathway to get there.

Something being a state function means that the pathway by which the value arrived at its final value does not matter in the calculation of the value.

A state function is a property that states that the path that something takes is irrelevant, the only thing that matters is the final result or final state. d

A state function doesn't rely on the pathway taken, it only relies on the initial and final values.

State functions only depend on initial and final values, thus intermediate steps are irrelevant when calculating enthalpy or entropy.

Could you also give examples of what would not be a state function?

Work is an example of a non-state (path) function
