moist air inside a room comes into contact with the colder window glass. The temperature difference makes the water vapor in the air cool down and change back into liquid, forming droplets.
1. A开篇第三句就是本题的答案:“The cycle of water from liquid to vapor to solid is called the water cycle.2.C蒸发的定义,这是一个物理变化,不是一个魔术,也不是物质消失,因此正确答案为C。3.B本题和第二题类似,理解了“condensation”的意思,根据我们的化学知识就可以得出答案。4. A “When the...
This technology and approach has been tested outdoors in Las Vegas, and is effective down to 10% humidity. It directly captures water in a liquid salt solution that is suitable for subsequent processing into drinking water or energy production, enabling new capabilities for arid regions. A key i...
This airborme moisture(水分) comes from A. Changing from water into ice water evaporating off oceans, lakes, rivers, plants, fallen rain and other B. Tuning into water from vapor.sources on Earth's surface. Winds in the atmosphere can then move that C. Turning from liquid into vapor....
Water is the only substance that occurs naturally as a solid (ice), a liquid and a gas (water vapor). It covers about 70 percent of the Earth for a total of approximately 332.5 million cubic miles (1,386 million cubic kilometers) [source: U.S. Geological Survey]. If you're familiar...

The water cycle works when the sun heats up a body of water and some of the water evaporates into the air. This might be water from lakes, streams, oceans, rivers, run off etc. The liquid water goes up into the air in the form of steam or vapor (water vapor). Condensation When ...
If there is a quantity of liquid water in the system the evaporation rate may freeze the water into ice. This lowers its vapor pressure which decreases the ability of the pumps to remove water from the system. The best procedure for eliminating water vapor in the vacuum chamber is to ...
A miniature cyclone was designed to gently capture fine aerosols into a continuous liquid flow. The geometry of the cyclone was designed so that the friction of the turning air swirls a 100 渭l volume of water at the base of the cone, creating a standing liquid vortex which coats the ...
