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...
The change of a solid into liquid is called ……… View Solution The conversion of a gas directly into solid is called condensation. View Solution The change in state of a liquid into solid is called ___ . View Solution The change of state from liquid to solid is called View Solution...
A common example of a solid substance undergoing a state-change directly to a gas (without melting first) is dry ice. Dry ice is solid carbon dioxide, and its weak intermolecular forces lead it to vaporize rather than form a liquid sta...
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 ...
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...
solid,liquid and gas 2.1 different types of substance基本的概念：必考内容 1.Matter：Matter is defined as anything that has___(质量)and occupy ___(体积).There are three types of matter ：Solid，Liquid and Gas Definition（定义）:Solid(s):has a ___（确定的） shape and___（体积） but ...
However, at the pressure where retrograde condensation begins the WDE turns forward thus acquiring a positive slope. This is because the light ends begin to vaporize and the waxes remaining in the liquid phase begin to concentrate. This is simply caused by the change in normal paraffin ...
Under high pressure, water reacts with methane to form solid methane hydrate which could lead to blocking of the pipeline if left unchecked. – In the presence of CO2 and/or H2S condensation of water in pipelines will lead to the formation of aqueous S2- ions and carbonic acid which will ...
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...
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 ...
