Does the second law of thermodynamics alter the conservation of energy principle?
The Second law of thermodynamics doesn’t alter the energy conservation principle because the total energy in a heat engine is constant.
The second law of thermodynamics states that converting heat energy to mechanical energy with 100% efficiency is impossible in a heat engine. This means that some kind of energy loss will take place.
According to the conservation of energy principle, energy can neither be created nor be destroyed, it can be transferred from one form to another. That means the total energy in an isolated system is constant.
The Second law of thermodynamics doesn’t violate the energy conservation theorem because energy is a constant. Total energy in a heat engine is the sum of work done and the energy given to the sink. So, the total energy remains constant. It transforms from thermal form to mechanical form.
So, the second law of thermodynamics doesn’t alter the energy conservation principle.
