In a method for changing gas into liquid by using devices such as a pump, materials to be changed into liquid are poured into a water containing part of a pump type compressor. The outer side of the liquid filled part is enclosed by the cooling water. Or, the materials are injected ...
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 process of water changing from a liquid to a gas is called ___. 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...
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...
Laminar boundary-layer flows of gas and liquid having a wavy phase-changing interface are analytically investigated to predict the features of their disturbance field. The basic field is approximated to be of linear profiles and perturbed with small wavy disturbances. The rate of phase-change at th...
