When a substance changes from a solid to a gas without passing through the liquid state, it is called ___. A. melting B. boiling C. sublimation D. condensation 相关知识点: 试题来源: 解析 C。物质从固态直接变为气态而不经过液态的过程称为升华。选项 A“melting”是熔化;选项 B“boiling...
A. Sublimation B. Evaporation C. Condensation D. Distillation 相关知识点: 试题来源: 解析 A。固体直接变为气体的过程称为升华(Sublimation)。“Evaporation”是蒸发,指液体变为气体;“Condensation”是冷凝,气体变为液体;“Distillation”是蒸馏。本题描述的是固体到气体,所以是升华,选 A。反馈...
Condensation method for a gas to precipitate a solid reactionPURPOSE: To simultaneously obtain a condensed solution having efficient contact and heat transfer performance and also to prevent deposition and solidification of crystals which deteriorate the condensation performance.坂田 英二...
Dry ice will go directly from a solid to a gas at room temperature. Going directly from a solid to a gas is called ___. (a) deposition (b) condensation (c) sublimation (d) solidification. The process of deposition describes which ...
The process when a solid changes directly to gas is called [{Blank}]. State the process by which solids change directly to gases and from gases to solids. What is it called when a liquid becomes a solid? a. condensation b. deposition c. evaporation d. freezing e. melting ...
Non-equilibrium gas to solid condensation produced three distinct groupings of ferrosilica solids with compositions ∽15, 30 and 87.5 wt.% FeO (or, ∽17, 33 and 97 wt.% Fe2O3). These solid compositions define metastable eutectic points in the FeO/Fe2O3–SiO2 binary system. The position...
根据第一自然段的 a liquid(water), agas (vapour) or a solid(ice)可知,水有三种形态,故选C。2.B细节理解题。题目问的是水的蒸发问题,所以将答案锁定在Evaporation部分。四个选项容易混淆,答题时注意辨析。3.D细节理解题。根据condensation(凝结)状态可知,蒸汽升入高空之后,随着温度的下降,会凝结成液态,然后...

After a certain number of recycling stages, these solid adsorbents gradually lose the adsorption function and need to be disposed of as hazardous wastes [33]. In addition, metal pipes and refinery equipment contaminated by mercury are also potential sources of mercury-containing solid wastes [34]....
