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...
A. evaporation B. condensation C. precipitation D. sublimation 相关知识点: 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...
Method in the utilization of boil-off from liquid gas and apparatus for carrying out the method In a plant for the production of fuel gas from boil-off and from liquefied gas with the aid of a combined heat exchanger (9), a compressor (4) is placed upstream of the heat exchanger in ...
A. evaporation B. condensation C. precipitation D. infiltration 相关知识点: 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,inf...

acondensation: the change of gas or vapor to a liquid;either by cooling or being subjected to increased pressure.When water vapor cools in the atmosphere,for example,it condenses into tiny drops of water,which forms clouds. 结露: 气体或蒸气的变动对液体; 通过冷却或被服从到增加的压力。例如时...
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...
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 ...
Since the molecules of a gas are much too far from each other to repel or attract each other it is very easy to compass a gas, while a solid or liquid is almost incompressible, because the repulsions of the electrical charges of which its atoms are made up are far stronger than any ...
