Which of the following makes the motion of a perpetual motion machine a physical impossibility?
Correct answer: B. second law of thermodynamics
- A. fist law of thermodynamics
- B. second law of thermodynamics
- C. third law of thermodynamics
- D. None of these
Explanation
As the second law of thermodynamics states, the more energy is transformed, the more is wasted. And for a perpetual motion machine to work, it has to have the energy that was never wasted, which makes it a physical impossibility.
