It's usually a combination of temperature,even air flow.

Now, I know how to relate the heat flow to temperature change, through the heat capacity.

现在我知道怎样把能量的流动,和温度的变化联系起来，通过热容。

If there's no heat flow between the b and c, then I can say all right, a and c were the same temperature.

如果在与之间没有热量流动，那么我就可以说，好吧与处于相同的温度。

You need a substance and then that substance has to have a property that changes depending on the heat flow, i.e., depending on whether it's sensing that it's the same temperature or different temperature than something else.

你需要某种物质,它的某种性质,随着热量的流动而改变，也就是说,依赖于它是否感觉到它,与其他的物体处于相同的温度。

the zeroth law, which is the common-sense law, which says that if you take a hot object next to a cold object, heat will flow from the hot to the cold in a way that is well defined, and it allows you to define temperature.

上节课我们讨论了，热力学第零定律,这一定律源自常识：如果把一个热的物体,与一个冷的物体挨在一起，热量就会以确定的方式。
