You have extensive properties and intensive properties The extensive properties are the ones that scale with the size of the system.

广延量,和强度量,广延量的值,随着系统的规模变化。

So the temperature is intensive, and you can make intensive properties out of the extensive properties by dividing by the numberof moles in the system.

所以温度是强度量，你可以通过,除以系统中物质的摩尔数,来从广延量中导出强度量。

These are called population measures because they refer to the whole population of possible outcomes and they measure the probabilities.
