Question

Difference between point function and thermodynamics property

Answer 1

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. Point Function: They depend on the state only, and not on how a system reaches that state. All propertiesare point functions

Answer 2

Explanation:

A point function is a property of the system or we can say all the properties of the system are point functions. ... Note: Since a point function is only dependent on the initial or final state of the system, hence in a cyclic process value of a thermodynamic function is zero, or change in thermodynamic property is zero.
