Entropy measures the amount of disorder in a physical system, such as the arrangement of molecules in a gas or atoms in a crystal. Entropy is calculated by finding the change in heat within a system and dividing it by th... More »

Entropy is the measure of the disorder prevalent in a dynamic system. Entropy is defined by the second law of thermodynamics as the amount of thermal energy flowing in and out of a system. It is a measure of the randomne... More »

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 »

Entropy means an increase of disorder or randomness in natural systems, and negative entropy means an increase of orderliness or organization. Negative entropy is also known as negentropy. Individual systems can experien... More »

Heat energy is determined by how active the atoms or molecules are in a substance. The atoms and molecules in a hot substance move rapidly and seem excited while the molecules and atoms in a cool substance show less move... More »
