The process of a substance changing from a solid to a gas is called ___. 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...
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 ...
