Entropy Sentence Examples

  • Changes of entropy must be calculated in terms of quantities of heat, and must be interpreted in a similar manner.

  • In the special case of a substance isolated from external heat supply, dH=o, the change of entropy is zero in a reversible process, but must be positive if the process is not reversible.

  • In practice, however, there is always some frictional dissipation, accompanied by an increase of entropy and by a fall of pressure.

  • Since the condition of heat-isolation is impracticable, the condition of maximum entropy cannot, as a rule, be directly applied, and it is necessary to find a more convenient method of expression.

  • Things tend to move toward disorder I think its called entropy or something that's Isaac's law.
