Question

what is entropy ??? explain .....​

Answer 1

Answer:

Entropy:

• It is the amount of energy which is unavailable to do work.
• tropy is a thermodynamic function.
• It usually defines the randomness and disorders of molecules.

Answer 2

Answer:

Entropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work.

Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.

The concept of entropy provides deep insight into the direction of spontaneous change for many everyday phenomena. Its introduction by the German physicist Rudolf Clausius in 1850 is a highlight of 19th-century physics.

The idea of entropy provides a mathematical way to encode the intuitive notion of which processes are impossible, even though they would not violate the fundamental law of conservation of energy.

For example, a block of ice placed on a hot stove surely melts, while the stove grows cooler. Such a process is called irreversible because no slight change will cause the melted water to turn back into ice while the stove grows hotter.
