Definition second law of thermodynamics

British Dictionary definitions for second-law-of-thermodynamics

law of thermodynamics

noun 1.

any of three principles governing the relationships between different forms of energy. The first law of thermodynamics (law of conservation of energy) states that the change in the internal energy of a system is equal to the sum of the heat added to the system and the work done on it. The second law of thermodynamics states that heat cannot be transferred from a colder to a hotter body within a system without net changes occurring in other bodies within that system; in any irreversible process, entropy always increases. The third law of thermodynamics (Nernst heat theorem) states that it is impossible to reduce the temperature of a system to absolute zero in a finite number of steps

2.

Also called zeroth law of thermodynamics. the principle that if two bodies are each in thermal equilibrium with a third body then the first two bodies are in thermal equilibrium with each other

FAQ

What is medical definition of second law of thermodynamics?

the entropy of the universe moves toward a maximum; similarly, the entropy of any isolated microcosm (for example, a chemical reaction) proceeds spontaneously only in that direction that yields an increase in entropy, entropy being maximal at equilibrium. To quote G.N. Lewis, "Every process that occurs spontaneously is capable of doing work; to reverse any such process requires the expenditure of work from the outside."
