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。
You need a functional form that connects the value at one state of matter, the freezing point of water to another phase change, the boiling point of water.
你需要一个函数形式来,连接物质某个态对应的温度值,如水的冰点,和另一个相变,如水的沸点。
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?
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。
What I am looking at here is boiling point as a function of atomic number.
我在看的是非典,作为原子序数的功能。
One of them here I happened to choose is boiling point versus atomic number.
其中之一,我已经选择的是,沸点及原子序数。
Why do they have a high melting point and boiling point?
为什么会有高熔点,和凝固点呢?
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。
