I'm going to write it like this three moles of hydrogen which is a gas one bar 100 degrees Celsius.
我会写成这样：,三摩尔氢分子，气体,1巴，100摄氏度。
-
It's hot, so Celsius right now, I think it's about 31 degrees.
很热，按摄氏度算的话，得有31度。

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。
-
My final stage is 50 degrees Celsius and one bar.
我的末态是50摄氏度，1巴。

Let's draw it in degrees Kelvin, instead of in degrees Celsius.
来重画一下这幅图，现在温度的单位是开尔文。
-
The lowest possible temperature in the Celsius scale is minus 273.15 degrees Celsius. So that begs the notion of re-referencing our reference point, of changing our reference points.
在摄氏温标中,绝对零度是-273。15摄氏度5,这样，我们需要重新定义参考点,将零度的参考点取在绝对零度处，而不是0摄氏度处。
-
And so redefining then the temperature scale to the Kelvin scale, where t in degrees Kelvin is equal to t in degree Celsius, plus 273.15.
以K为单位的温度,是以℃为单位的温度,加上273。15度。
-
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。
