Entropy is a measure of the disorder present in a system. Entropy is disorder or randomness.

Entropy is a thermodynamic quantity, its value is equal to the amount of **heat** absorbed or emitted divided by the thermodynamic **temperature** (the absolute temperature, in Kelvin). The units of entropy are joules per Kelvin per **mole**. In chemical equations entropy is normally given the symbol S. The higher the entropy value the more disordered a system is, so for example of the three states of **matter** a gas, with the greatest degree of disorder, has the highest entropy value. Next are **liquids** and finally of the three **states of matter** the most ordered form are the **solids** and they have the lowest degree of entropy. Any change that increases entropy is a positive entropy change. Most spontaneous thermodynamic processes are accompanied by an increase in entropy.
