Raoult's law

例句：

1. 1. The concentration of the solution is directly proportional to the volume of the solvent used.
   溶液的浓度与所用的溶剂体积成正比。
2. 2. This phenomenon is consistent with Raoult's law, which states that the concentration of a solution increases as the volume of the solvent decreases.
   这种现象符合拉乌尔定律，该定律指出，溶剂体积减小时，溶液浓度会增加。
3. 3. In this experiment, we found that the concentration of the solution increased as the volumeof the solvent decreased, which is consistent with Raoult's law.
   在这个实验中，我们发现溶液浓度随着溶剂体积的减小而增加，这与拉乌尔定律相符。
