溶液的蒸气压降低（Lowering the vapor pressure）-核心 1)在一定温度下，向纯溶剂中加入难挥发性的溶质，此溶液的蒸气压仍然是溶剂的蒸气压 2)在一定温度下，溶液的蒸气压小于纯溶...

So, that means that the vapor pressure above the solution is lowered. So I should have said vapor pressure lowering.
这就表示溶液上的，蒸汽压下降，所以这就是刚才说的饱和蒸汽压下降。
Colligative properties are the properties like the vapor pressure, lowering when you have a mixture in a liquid, instead of having a pure substance you have amixture of substances here.
依数现象是这样一种现象,当你把物质混合在一起的时候,你不会得到纯物质,而是得到混合物质。
It's going to come from the vapor pressure lowering not from the osmotic pressure, which we'll do next.
我们可以从蒸汽压得变化，而不是渗透压，得到这个结果。
