A. Sublimation B. Evaporation C. Condensation D. Distillation 相关知识点: 试题来源: 解析 A。固体直接变为气体的过程称为升华(Sublimation)。“Evaporation”是蒸发,指液体变为气体;“Condensation”是冷凝,气体变为液体;“Distillation”是蒸馏。本题描述的是固体到气体,所以是升华,选 A。反馈...
When it is a liquid, it can run 2 your fingers. When it is a gas, you may not 3 or feel it. Water can change from a solid to liquid or to a gas 4 . This is why we always have fresh water. Now let us find out 5 it changes. The heat of the sun turns liquid water into...
所以选A.
【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 gas ...
