Path function: Their magnitudes depend on the path followed during a process as well as the end states. Work (W), heat (Q) are path functions. The cyclic integral of a point function is zero. properties are point functions, (ie pressure,volume,temperature and entropy)
Point Function: They depend on the state only, and not on how a system reaches that state. All properties are point functions. The cyclic integral of a path function is non-zero. work and heat are path functions.
