Question

Of the following, which one is a state function?

A. heat
B. H
C. q
D. w
E. none of the above

Answer 1

The internal energy of a system is a state function, while heat and work are not state functions on their own.

Step-by-step explanation:

According to the first law of thermodynamics, the internal energy (AU) of a system is a state function. Heat (q) and work (w) are not state functions on their own. However, their sum (AU = q + w) is a state function because it depends only on the initial and final states of the system, regardless of the path taken to reach those states.
