Correct Answer - Option 2 : Work

CONCEPT:

Point function:

  • Point function (also known as state function) is a function whose value depends on the final and initial states of the thermodynamic process, irrespective of the path followed by the process.
  • Example: pressure, temperature, internal energy, volume​ , etc.


Path function:

  • A Path function is a function whose value depends on the path followed by the thermodynamic process irrespective of the initial and final states of the process.
  • Example: work, heat, etc.


EXPLANATION:

  • From the above explanation, we can say that internal energy, temperature, and volume are point functions, so they depend on the initial and the final stage of the process.
  • But the work is a path function so it depends on the path of the thermodynamic process. Hence, option 2 is correct.
