突发奇想,学生们是否需要一本口袋书,把理科科目的学术词汇和概念汇集起来,随身携带便于记忆。记得小编小时候就有一个英语词典,名片盒大小,放在口袋里(有时会拿出来装模作样看看)。今天的主题是一种分离方法,蒸发。
✏ solution 溶液
✏ solvent 溶剂
✏ solid residue 固体残留物
✏ soluble solid 可溶性固体

Evaporation is the process by which water and other liquids changes from a liquid state to a vapor or gas state.
Evaporation is great for separating a mixture solution of a soluble solid such a table salt and a solvent such as water.
The process involves heating the solution until the solvent evaporates turns into a gas, leaving behind the solid residue.

蒸发是水(和其他液体)从液态变为蒸汽或气态的过程。
蒸发非常适合分离可溶性固体(如食盐)和溶剂(如水)的混合物溶液)。这个过程需要加热溶液直到溶剂蒸发,变成气体,留下固体残留物
