If I get you down to a cluster of about 30 water molecules, the boiling point is a function of the size of the water droplet.

如果对于一个由30个水分子,组成的簇，沸点是,水珠尺寸的函数。

Our temperature probably fluctuates during the day a little bit anyways, it's not very accurate. And similarly, the boiling point, defining that at a 100 degrees Celsius well that depends on the pressure.

这就不太精确,我们的体温一天之中，会有高低的变化，这一定义不够精确,类似的,我们把水的沸点定义为。

If everything is the same, you know, when you were a kid someone would say, which has a higher boiling point, a quart of water or a gallon of water?

如果每个东西都一样，当你是个还是一个孩子的时候，有人说，那个有更高的沸点，1夸脱水还是1加仑水？

Water boils at different temperatures, depending on what the atmospheric pressure is; same thing for the freezing point.

丹佛和波士顿水的沸点，就不一样;,在不同的大气压下。

The reference points are water freezing or boiling, and the interpolation is linear and then that morphed into the Kelvin scale as we're going to see later.

参考点是水的冰点和沸点,插值是线性的,随后它被发展成为开氏温标,我们之后会看到。

So, you assign values to very specific states of matter and call those the reference points for your temperature. For instance, freezing of water or boiling of water, the standard ones.

那么你对物质的,某些特殊状态指定数值,把它们叫做你的温度的参考点,比如水的冰点或沸点,它们都是标准。

Then he interpolated and found out water boils at 212.

然后他做了插值,发现水的沸点是212度。

So that means, then, you've got to define the pressure pretty well.

水的沸点也不一样，水的冰点的情况也一样。

And Celsius first used the boiling point of water, and called that 100 degrees Celsius, and the freezing point of water and called that zero degrees Celsius.

定义一些参考点，例如摄氏温标定义水的沸点，是100摄氏度,冰点是0摄氏度。
