The process by which a solid changes directly into a gas without passing through the liquid state is called ___. A. evaporation B. condensation C. sublimation D. deposition 相关知识点: 试题来源: 解析 C。解析:“sublimation”是升华,固体直接变为气体不经过液态的过程是升华;“evaporation”是蒸发...
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...
