And if you go back into the 1800's when thermodynamics was starting, there were a zillion different temperatures scales Everybody had their own favorite temperature scale The one that we're most familiar with is the centigrade or Celsius scale where mercury was the substance, and the volume of mercury is the property.

如果你回头看看19世纪温度计,刚开始使用的时候，那时有不计其数的不同温标,每个人都有他们自己最喜欢的温标,我们最熟悉的是,摄氏温标，用水银,作为工作物质，水银的体积是所用的性质。
