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 »

Thermodynamics is the study of the energy and work of a system. It deals with only the large scale response of systems, which are observable and measurable. Thermodynamics has three principal laws: the zeroth law, the fi... 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 »

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 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 »
