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。
zero gravity experiments/ gas phaseliquid phaseThe behavior of gases and liquids during a phase transition is severely affected by gravity effects which unavoidably drive the denser phase downwards and the lighter phase upwards. When such gravity effects are suppressed a number of new and surprising...
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 ...
In this chapter, we bridge our discussions of the gas and the liquid by considering several aspects of the vapor pressures, P sat, of the two helium isotopes. The P sat vs. T relations for He3 and He4 relative to some fixed absolute temperatures establish convenient and practical temperature...
Above the critical point the liquid and the gas can no longer be (15)___; there is a single, undifferentiated fluid phase of uniform density. A.in the event ofB.in the case ofC.with a view toD.with reference to相关知识点: 试题来源...
aThe experinents demonstrate that the gas-liquid reaction becomes gas film controlling as the cobalt ethylenediamine concentration exceeds when there is 1200 ppm SO in the gas phase experinents显示出,气液的反应成为气体影片控制,当钴乙二胺含量超出,当如此有1200 ppm在气相[translate]...
Propene acetoxylation in the liquid phase-influence of technological parameters and pretreatment of the catalyst support on the course of the process The novel and more safe method for propene acetoxylation has been developed. The reaction is conducted in the liquid environment of acetic acid, which...
Although energy storage by latent heat can be utilized by changing of phase from liquid to gas, the transition from liquid to gaseous phase requires a significant pressure and volume rise [[23], [24], [25]]. Because of its large capacity to absorb thermal energy, the use of PCM in STH...
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...
Air was fed into the channel from its inlet, while liquid water was injected uniformly into the channel along the permeable sidewall. Based on the results of visualization, the typical flow patterns encountered in the conventional co-current gasliquid two-phase flow were not observed in the ...
