Entropy is seen in situations that involve the dispersal of energy from a concentrated state to a less concentrated one, such as a hot pan cooling down, a tire blowing and releasing its air, the rusting of metal or cream... More »

High entropy is a high level of disorganization in a physical system, such as molecules in a gas. Entropy is a quantity used by physicists to describe how organized systems are on the atomic and subatomic level. More »
