A. evaporation B. sublimation C. condensation D. deposition 相关知识点: 试题来源: 解析 B。sublimation 是物质从固态直接变为气态的过程,叫升华;evaporation 是蒸发,通常是指液体变为气体;condensation 是冷凝,是气体变为液体;deposition 是沉积,通常是指气态变为固态。反馈...
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...
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 ...
Describe all the state of changes that solid caffeine passes through in order to become a gas. What is it called when a gas becomes a solid? a. condensation b. deposition c. evaporation d. freezing e. melting f. sublimation What is it called when a solid...
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 ...
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 ...
(on mole basis). As the isobar of 5MPa is indicated by bold curve, for example, the liquefaction flow of NG can be divided into three regions by the phase: pre-cooling (vapor), condensation (phase change), and sub-cooling (liquid). The specific heat has a sharp peak around 200K, ...
The sampling phase must (1) reduce particle concentrations to levels suitable for the measurement instruments, and (2) prevent condensation of gases on the surfaces of the sampling system itself or inside the measurement instruments. Often particles of a certain degree of volatility are of special ...
Briefly and by way of an explanation that relates to the properties of the liquid,gas condensateis a mixture of low-boiling hydrocarbon liquids obtained by condensation of hydrocarbon vapors: predominately butane, propane, and pentane with some higher molecular weight hydrocarbon derivatives and relativ...
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 ...
