The role of the principle of minimum energy
Because of the principle of minimum energy, all energy flows from high to low. According to the second law of thermodynamics, energy is directional. Any spontaneous reaction will conserve energy, but the entropy will become larger because of the energy difference. With the conversion and transmission of energy. When these energy differences are used up by us, that is, when all the energies in the universe are equal, it is called thermal silence.
