Snowforms mainly when water vapor(蒸气) turns to ice without going through the liquid stage. This process is called deposition(凝华). Snowflakes that most of us are used to seeing are not individual snow crystals, but are actually aggregates(聚集体), or collections, of snow crystals that sti...
Condensation is when you change water vapor to liquid. Or sometimes we use that word also when we're condensing it to ice. But usually it's used when we condense it to liquid. Evaporation is the reverse of that. It's when you take water in the liquid form and evaporate it, put it...
Liquid water changes to vapor, is called evaporation. (用适当的词填空) 相关知识点: 试题来源: 解析 which 【详解】 考查定语从句。句意:液态水变成蒸汽,称为蒸发。分析句子结构和意思可知,此处是非限制性定语从句,先行词是整个主句的内容,在从句中作主语,用关系代词which引导。故填which。
When vapor cools down and changes back into liquid water, it is ___. A. condensation B. evaporation C. precipitation D. collection 相关知识点: 试题来源: 解析 A。选项 A“condensation”是凝结,水蒸气冷却变回液态水是凝结过程;选项 B“evaporation”是蒸发;选项 C“precipitation”是降水;选项 D“c...
When heated, water changes into ___.A. solid B. vapor C. liquid D. air 相关知识点: 试题来源: 解析 B 加热后,水就会变成蒸汽。答案 BA solid 固体的,实心的,结实的,坚固的B vapor 蒸汽 水汽C liquid 液体的,液态的,流动的D air 空气反馈 收藏...
