What's the definition of a state property?

A state function is a property that depends only on the current state of the system and is independent of how the state was prepared.

A state function does not depend on the path taken to achieve that state. This includes density, internal energy, enthalpy, etc.

A state function only depends current conditions, not the path it takes to get there.

A state function is a property whose value does not depend on the path taken to reach a specific value. For the sake of this class, pressure, density, temperature, volume, enthalpy, internal energy, Gibb's free energy, and entropy are state functions.

A state function is a function which does not depend upon the path taken to reach a particular final point. Observations of the behavior are valid by simply looking at the final and initial point. An example of a state property Entropy

A state property is one where the start and the end of the function only matter rather than the path taken.

A state function is something where the path doesn't matter, only the initial and final state. The reason it is so important is that since the path doesn't matter, you can subtract, add, multiply, and divid state functions as necessary.
