So, the active part of the thermometer could be water. It could be alcohol, mercury, it could be a piece of metal.
那么温度计的工作部分,可以是水可以是酒精,水银,可以是一块金属。
The Romer scale was, Romer was a Dane, and he defined freezing of water at 7.5 degrees Roemer, and 22.5 degrees Romer as blood-warm.
他的罗默温标,定义水的冰点,是7。5,罗默度,温血的温度是22。5,罗默度。
You ignite the food and burn it, and you see how many degrees centigrade the water gets raised, and that's the measure of calories.
点燃食物使其燃烧,然后观察水的温度上升了多少,就测量了这种食物的卡路里
And you can find these compressibility factors in tables. If you want to know the compressibility factors for water, for steam, at a certain pressure and temperature, you go to a table and you find it.
各种气体的压缩系数,想知道水或者水蒸气,在某个温度和压强下的,压缩系数,查表就行了,这是实际气体状态方程的。
And our other reference point is the triple point of water - reference points become zero Kelvin, absolute zero, and the triple point.
而使用绝对零度,它与压强无关,是最低的温度,另一个参考点是水的三相点。
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。
And the triple point of water is 16K that temperature and pressure - there's a unique temperature and pressure where water exists in equilibrium between the liquid phase, the vapor phase, and the solid phase.
与水的三相点,我们定义它为273。,水的三相点,是一个特定的温度和压强,可以使水的液态,气态和固态三相共同达到平衡,三相点是液态。
