Importance of Entropy

Importance of Entropy

If you have taken Chemistry or physics, you learned what Entropy is all about.

By definition, entropy is simply a measure of randomness (uncertainty) or disorder in a collection of objects or energy; symbolized by S.

Typical example would be when you place an ice cube on a table in room temperature, the ice cube

would melt due to the room temperature, and thus the randomness of the particles increase, because the heat

causes the particles to be free and moving into open space.

The importance of Entropy is because without this law (the spontaneity in our world), there is no single

reaction in our world therefore, nothing will occur.
