水蒸气

水蒸气使镜子变得模糊不清。

Steam had clouded the mirror .

水蒸气触及冷的表面即凝结成水。

Steam condenses to water when it touches a cold surface .

两种主要的燃烧产物是水蒸气和二氧化碳。

The two principal combustion products are water vapor and carbon dioxide .

水蒸气凝结形成云。

Water vapour condenses to form clouds

云是由大气中的水蒸气凝结成的。

A cloud is a condensation of water vapour in the atmosphere .

水蒸气凝成了小水滴。

Steam condenses into drops of water .

冷风使水蒸气凝结成雨。

The cold wind condenses vapor into rain .

水蒸气、水和冰是同一物质的三个相态。

Steam , water and ice constitute the three phases of the same matter .

"不管你是河流还是水蒸气,你的本性永远不会改变。"

" And whether you 're a river or vapor , your nature never changes . "

无论你是河流还是水蒸气,你的本性永远不会改变

" And whether you are a river or vapor , your nature never changes ． "

我们知道，水蒸气遇冷之后就会产生冷凝。

We have learned that when water-vapour is cooled it is condensed .

他一走进暖房，眼镜就被蒙上一层水蒸气。

His glasses steamed up when he came into the warm room .

因此，当水蒸气再次变成水滴的时候，淡水应运而生。

So when this vapour is changed back into water again , it forms pure fresh water .

科学家们此前已经在月球上发现了冰存在的迹象，也在月球稀薄的大气中发现了水蒸气存在的迹象。

Scientists have previously1 found signs of ice on the Moon and water vapour in its thin atmosphere .

其实，它们与那些从沸腾的水壶中冒出的白色水蒸气一样。

They are just like the clouds of white steam , as we call it , that you see rising from a boiling kettle .

靠近地球表面的空气温度比高空的空气温度要高一些，因此，当水蒸气漂浮到高空时就会被冷却。

The air near the surface of the earth is warmer than that which is higher up , so when the water-vapour rises very high above the ground , it is cooled .

因此，水蒸气首先变成了非常细小的水粒——也就是我们所说的水雾——并构成了云朵，然后这些水粒汇聚在一起成为了雨滴。

So the water-vapour is first changed into those very tiny specks of liquid water which have been called water-dust , and appears as clouds ; and then these specks of water join together to form drops of rain .
