The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed, only transferred or transformed from one form to another. The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, and it tends to increase until it reaches equilibrium.
