Water can exist in three states: solid, liquid, and gas. When water freezes, it turns into ice, which is the solid state. When water boils, it turns into steam, which is the gas state. The process of water changing from a liquid to a gas is called ___. A. evaporation B. condens...
【小题1】根据第一段When it is a solid, it can be as hard as stone. 描述,结合常识可知当水是固体时,它被叫做冰,故选D,冰。【小题2】根据第一段When it is a gas, you may not see or feel it. 描述,可知选C。【小题3】根据第二段The heat of the sun turns liquid water into ...

When a gas is turned into a liquid, the process is called? What is latent heat of vaporization of water? Is the latent heat of vaporization of water used for the boiling and evaporation process? What is the concentration of water vapor?
Most of the water goes back to the rivers, seasand oceans .This process then starts all overagain . T his process is called the water cycle.(1)What are the forms of most matter?solid, rock, ice .liquid, gas, solid .gas, rock, steam .water, ice, steam .(2)What may happen ...
根据第一段第一句“Water can be a liquid, a solid or a gas.(水可以是液体,固体或者气体。)”可知,物质的三种形态是“液体,固体、气体”,所以B项正确。 (2)【答案】B 【解析】题干的意思是“当云上升时可能发生什么? .”A.它们上升得越高,就被加热得越多;B.它们上升得越高,就被冷却得越多;C...
Gas−liquid phase transformation is mainly realized through the form of heat pipe. Heat pipes transfer heat mainly through the circulation of liquid in a sealed container. In practice, heat pipes need to be in close contact with batteries. At present, solid−liquid transformation is mainly ...
