There's the water phase, there's the ice cube is the solid phase, and there's some water, gas, vapor, and that's one bar.
里面放一块冰，这是固态；,于是我们得到了水，冰和水蒸气三态共存的点。
-
And, even Cavendish, one of the things that he observed was that hydrogen could be combusted to produce water vapor.
甚至卡文迪许都观察到了,氢气燃烧,会产生水蒸气。
-
There's hardly any vapor pressure above your ice water glass.
冰水混合物上方,水蒸气的气压非常小。
-
The first thing I am going to do is I am going to convert the sodium into vapor.
第一步,我将要将固态的钠气化。
-
So, if you start with sodium vapor and chlorine gas, electron transfer will occur.
所以，如果从以钠蒸汽和氯气开始，电子传递就会发生了。
-
Water vapor goes through my skin.
水蒸气会穿过我的皮肤。
-
This process is sublimation, solid to vapor.
从固态到液体的这个过程，叫做长华。
-
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。
-
When you go down the highway and you look up and see those sodium vapor lamps, the sodium vapor exists as the dimer Na2.
你在下高速公路时,会看到一些钠蒸汽灯，蒸汽灯中钠就有以Na2存在的。
-
And so, you make not only water vapor, NOX but you make some nitrous oxides, NOX, or nox as it is known, and this is the precursor to smog.
这样不仅仅得到的水蒸气，但是你会得到一些氮氧化物，或者如大家所知到的nox，这是烟雾的前驱体。
