What Does Thermodynamics, Second Law Mean?
The second law of thermodynamics explains the quality of energy in a cyclic process. The law states that in every natural thermodynamic process, the entropies of all the participating bodies increases. This means that in a cycle where energy is being changed from one form to another, each time the energy changes form, some is lost or wasted.
Safeopedia Explains Thermodynamics, Second Law
Entropy in thermodynamics refers to the loss of energy as it is transformed, due to the natural tendency for any isolated system to descend into disorder. The second law of thermodynamics states that in any process entropy increases and everything becomes less orderly by nature. In thermodynamics, the discussion of any transfer of energy involves thermal energy or heat energy.
