The first law of thermodynamics is a statement of the law of conservation of:
Correct answer: C. Energy
- A. Mass
- B. Heat
- C. Energy
- D. All
Explanation
The first law of thermodynamics states that energy cannot be created or destroyed in an isolated system. It can only change forms. Therefore, it is a statement of the conservation of energy.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
