What's the difference between amount and entropy?

Amount


Definition:

  • (n.) To go up; to ascend.
  • (n.) To rise or reach by an accumulation of particular sums or quantities; to come (to) in the aggregate or whole; -- with to or unto.

Entropy


Definition:

  • (n.) 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.

Example Sentences:
