State function - Properties of the system that are independent of the history of the system. The values of these variables can be calculated from knowledge of the present state of the system, without knowing its history.
A state function means it is path independent. It does not matter how you get there.

State variables are the parameters which define the state of the system at any time t.
Generally these are Pressure(P), Volume(V) and Temperature (T).
