First law of thermodynamics concerns with the conservation of:
Correct answer: D. Energy
- A. Heat
- B. Work
- C. Momentum
- D. Energy
Explanation
The correct statement is D. Energy. The first law of thermodynamics concerns the conservation of energy, stating that the total energy of an isolated system remains constant, and energy can be transferred between various forms but cannot be created or destroyed.

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.
