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。
A. condensation B. evaporation C. freezing D. melting 相关知识点: 试题来源: 解析 B。解析:文章中提到“When water is heated to a certain temperature, it turns from a liquid to a gas. This process is called evaporation.”,所以水从液态变为气态是通过蒸发过程。反馈 收藏 ...
The process of water changing from a liquid to a gas and then back to a liquid again is part of the ___. A. water cycle B. weather cycle C. seasonal cycle D. life cycle 相关知识点: 试题来源: 解析 A。水从液态变为气态再变回液态是水循环的一部分。选项 B 天气循环说法不准确;选项...
A. condensation B. evaporation C. precipitation D. sublimation 相关知识点: 试题来源: 解析 B。本题考查水循环的过程。水从液态变为气态的过程叫做蒸发。A选项凝结是气态变为液态;C选项降水是水汽凝结后落下的过程;D选项升华是固态直接变为气态。反馈 收藏 ...
