Answer:
Second law of Thermodynamics
Explanation:
The reason is that the not whole of the energy utilized by the firm is converted into work done. The greater part of the energy is wasted and is in-accordance with nature. If we start running we get warmer because some of our body energy is wasted. It is also evident that the diesel engine efficiently converts 36% of the total fuel and the rest of the energy is wasted because of the heat generated by the engine. Thats in-accordance with second law and the main reason why 84% of energy is wasted.
