In Chemistry, the work is generally:
Correct answer: C. Pressure - Volume Work
- A. Done by temperature change
- B. Pressure - Temperature Work
- C. Pressure - Volume Work
- D. None of these options is correct
Explanation
The work is pressure-volume work. Pressure-volume work is the work that is done by the compression or expansion of a fluid. Whenever there is a change in volume and external pressure remains constant, pressure-volume work is taking place. Work is the energy required to move something against a force.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
