Which from following is NOT a state function ?
- AVolume
- BPressure
- Correct answerCWork
- DTemperature
Solution
State functions are properties whose values depend only on the state of the system and are independent of the path followed to reach that state.
Pressure, volume, and temperature are state functions because they depend only on the initial and final states of the system.
Work and heat are path functions because their values depend on the specific path taken to go from the initial state to the final state.
Therefore, work is not a state function.
Answer: Work
Pressure, volume, and temperature are state functions because they depend only on the initial and final states of the system.
Work and heat are path functions because their values depend on the specific path taken to go from the initial state to the final state.
Therefore, work is not a state function.
Answer: Work
Hence, the correct answer is option: 'C'.
