The first law of thermodynamics is a restatement of the law of conservation of:
- A.Momentum
- B.Energy
- C.Mass
- D.Entropy
Show correct answer & step-by-step solution
Correct answer: B — Energy
Solution
The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another. This is fundamentally the law of conservation of energy applied to thermodynamic systems.
