Question

What is meant by entropy?​

Answer 1

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.

Answer 2

Explanation:

Entropy is defined as the measure of degree of disorder or the Thermodynamic Representation of randomness of a system.

• It is a stare function since it depends on the state of a system.

• It is designated by symbol 'S'.

• Apart from depending on state of the system,entropy also depends on temperature.

• If entropy increases then the randomness of a particle also increases.

Example:-

• ice kept on a plate forms water
