A thermodynamics state function is a quantity-

A

used to determine heat changes

B

whose value is independet of path

C

used to determine pressure-volume work

D

whose value depends on temperature only

Text Solution

Verified by Experts

The correct Answer is:
B
A thermodynamic state functionn of a system is a quantity whose value depends only on the present state of the system. Its value does not depend on the path of a process in which the system participates.
