【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 ...
【题目】水的形态Water can be a liquid, a solid or a gas. When it is a solid,it can be as hard as stone. When it is a liquid, it can runthrough your fingers. When it is a gas, you may not see orfeel it.Water can change from a solid to aliquid or to a gas easily. Th...
A. evaporation B. condensation C. sublimation D. deposition 相关知识点: 试题来源: 解析 A。解析:“evaporation”是蒸发,液体变为气体的过程叫蒸发;“condensation”是冷凝,气体变为液体;“sublimation”是升华,固体变为气体;“deposition”是沉积,气体变为固体。反馈 收藏 ...
结果一 题目 All matter,() it is a gas,a liquid or a solid,expands as the temperature rises A.whether B.whatever 答案 答案选A.whether相关推荐 1All matter,() it is a gas,a liquid or a solid,expands as the temperature rises A.whether B.whatever ...
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...
A. evaporation B. condensation C. sublimation D. precipitation 相关知识点: 试题来源: 解析 A。本题考查科学术语。evaporation 是“蒸发”,即从液体变为气体的过程;condensation 是“凝结”,从气体变为液体;sublimation 是“升华”,从固体直接变为气体;precipitation 是“降水”。反馈 收藏 ...
试题来源: 解析 A。本题考查科学概念的英文表述。“evaporation”意思是蒸发,液体变为气体的过程就是蒸发。B 选项“condensation”是凝结,是气体变为液体的过程。C 选项“precipitation”是降水。D 选项“sublimation”是升华,是固体直接变为气体的过程。反馈 收藏 ...
试题来源: 解析 A。解析:蒸发(evaporation)是水从液态变为气态的过程,这符合题目描述。选项B,condensation是气态变为液态的凝结过程,与题目要求不符。选项C,precipitation是降水过程,包括雨、雪等形式,不是液态到气态的转变。选项D,infiltration是入渗过程,指水渗入土壤等,和液态到气态的转变无关。
The difference between a liquid and a gas is obvious (1)___ the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and (2)___it to the level of a free surface. A gas forms no free surface but (3)___to ...
