acondensation: the change of gas or vapor to a liquid;either by cooling or being subjected to increased pressure.When water vapor cools in the atmosphere,for example,it condenses into tiny drops of water,which forms clouds. 结露: 气体或蒸气的变动对液体; 通过冷却或被服从到增加的压力。例如时...

The point at which a liquid's surface pressure equalizes the air pressure above (atmosphere). The temperature-dependent increase in vapor pressure shows the material's propensity to transform into vapors.Answer and Explanation: A liquid's gas pressure over the surface is kn...
1,water vapor in the air condenses when the air is chilled because water molecules move more slowly,thus are more likely to stick together.a)trueb)false2,why does warm moist air form clouds when it rises?a)as air rises it expands and cools...

When a liquid such as water turns into vapor, the process is called evaporation. The reverse process is called condensation. At low temperatures, water will condense out of the air into very small droplets of water. Clouds Clouds are actually very small droplets of water (or possibly even ice...
Rain falls when water vapor in clouds condenses(凝结). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates(蒸发) some of the water in the ground and in the ...
Why are liquids usually difficult to compress? Explain why water vapor turns into a liquid as it cools. Why does temperature increase when water condenses? Why is water liquid at room temperature? Why is a gas easier to compress than a liquid or a solid?

back to the atmosphere. Meteorologists call this the water cycle. There are many stages in the water cycle. Rain falls when water vapour in clouds condenses(冷却成液体). Drops of water form and fall to the ground. The water soaks into the ground and feeds streamsand rivers. A lot of ...
