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 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 »

The International System of Units states that entropy has a unit of Joules/Kelvin. It always has the dimensions of energy divided by temperature and can be measured in a myriad of units as long as they fit that criteria. More »

Entropy decreases as a result of applying energy to a system to increase its order. However, entropy only decreases locally; the result of the work that decreases the entropy in one location emits other forms of energy e... 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 »

The second law of thermodynamics states that the entropy, or disorder, of a closed system has a tendency to increase. Restoring order to an entropic system by separating the oxygen from the nitrogen in a room, for exampl... More »
