second law of thermodynamicsnoun
a law stating that mechanical work can be derived from a body only when that body interacts with another at a lower temperature; any spontaneous process results in an increase of entropy

second law of thermodynamics
The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time and remains constant if and only if all processes are reversible. It also posits that the entropy of such a system spontaneously increases towards a maximum value, often leading to the conclusion that energy in the universe naturally disperses or spreads out from areas of high concentration to low concentration. This law helps to explain the natural direction of flow of energy and the concept of irreversibility in natural processes.

Second law of thermodynamics
The second law of thermodynamics states that the entropy of an isolated system never decreases, because isolated systems spontaneously evolve towards thermodynamic equilibrium—the state of maximum entropy. Equivalently, perpetual motion machines of the second kind are impossible. The second law is an empirically validated postulate of thermodynamics, but it can be understood and explained using the underlying quantum statistical mechanics, together with the assumption of low-entropy initial conditions in the distant past. In the language of statistical mechanics, entropy is a measure of the number of microscopic configurations corresponding to a macroscopic state. Because equilibrium corresponds to a vastly greater number of microscopic configurations than any non-equilibrium state, it has the maximum entropy, and the second law follows because random chance alone practically guarantees that the system will evolve towards equilibrium. It is an expression of the fact that over time, differences in temperature, pressure, and chemical potential decrease in an isolated non-gravitational physical system, leading eventually to a state of thermodynamic equilibrium.
