Heat, Work & First Law of Thermodynamics

Which of the following parameters does not characterize the thermodynamic state of mattter?

Show answer and solution

Answer: (c)

State variables ( $P$ , $V$ , $T$ ) describe the condition of the system at one instant.
Work depends on the path between states, so it is not a state variable.
So the answer is (c) Work.
