2. Entropy
   A measure of the number of possible states a group of 'somethings can occupy' - the more possible ways the group can be arranged, the higher the entropy. For example, there are fewer possible configurations of students in chairs in a room where the chairs are bolted to the floor than where the chair...

9. Entropy
   The average amount of information represented by a symbol in a message, is a function of the model used to produce that message and can be reduced by increasing the complexity of the model so that it better reflects the actual distribution of source symbols in the original message. Entropy is a meas...

10. Entropy
    a measure of the unavailability of the thermal energy within a system for conversion into mechanical work All energy transformations (i.e. chemical to chemical, chemical to thermal) increase entropy.

12. entropy
    (S) Entropy is a measure of energy dispersal. Any spontaneous change disperses energy and increases entropy overall. For example, when water evaporates, the internal energy of the water is dispersed with the water vapor produced, corresponding to an increase in entropy.

13. entropy
    Entropy (S) is a measure of the unavailability of a system's energy to do work; in a closed system, an increase in entropy is accompanied by a decrease in energy availability. When a system undergoes a reversible change the entropy (S) changes by an amount equal to the energy (Q) transferred to the ...
