- Gradual decline into chaos - Lack of order - A certain property of a body, expressed as a measurable
quantity, such that when there is no communication of heat the quantity
remains constant, but when heat enters or leaves the body the quantity
increases or diminishes. If a small amount, h, of heat enters the body
when its temperature is t in the thermodynamic scale the entropy of the
body is increased by h / t. The entropy is regarded as measured from
some standard temperature and pressure. Sometimes called the
thermodynamic function.
