entropy - KFUPM Faculty List
... Qualitatively, the entropy (S) of a system is a measure of how spread out or how dispersed the system’s energy is. The simplest interpretation of this is how spread out a system’s energy is in space. In other words, for a given system, the greater the volume it occupies, the greater its entropy. ...
