Point Function and Path Function

Point Function

Point Function are the properties which depends on the initial and final state of the system & not on the path followed by the system while undergoing change of state. All the properties of the system are point function.

Path Function

These are the characteristics which are not property of the system & depends upon the path followed by the system while undergoing change of state. If the initial and final state remain the same but path followed varies then value of these quantities also changes. Example- work transfer, heat transfer.
