When a solid is converted directly to a gas, the change of state is called ___. Phase transition Generally a solid first converts into a liquid and then into a gas. But under certain conditions of temperature and pressure, certain compounds turn directly to ...
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 f. sublimation For the phase change of liquid to solid, what are the si...
When a solid changes directly into a gas, it is called ___. A. evaporation B. condensation C. sublimation D. precipitation 相关知识点: 试题来源: 解析 C。sublimation 是固体直接变为气体的过程;evaporation 是液体变为气体;condensation 是气体变为液体;precipitation 是降水。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 收藏 ...
Subsequently, the catalyst lifetime is directly related to the level of sulfur removal in the gas cleaning process. One of the well-known methanation unit designs is TREMP by Haldor Topsoe [70]. Syngas is mixed with a recycle stream and fed to the first reactor. The effluent is collected ...
(12)) that the rate of gas hydrate deposition is directly proportional to the molecular weight of gas hydrate but inversely related to molecular weight of the gas. The effective inner radius of the pipeline can be calculated as follows: (13)rf=rti−∫0tuk1ΔTsubρhe−k2/Tfdt The sub...
The change of a substance from a solid directly to a gas is referred to as ___. Phases of Matter: Matter can be classified into three primary phases: solid, liquid, and gas. Through advanced science, more phases such as plasmas and Bose-Einstein condensates have bee...
