水的饱和蒸汽压与温度对应表

水的饱和蒸汽压与温度对应表 蒸气压蒸气压指的是在液体（或者固体）的表面存在着该物质的蒸气，这些蒸气对液体表面产生的压强就是该液体的蒸气压。比如，水的表面就有水蒸气压，当水的蒸气压达到水面上的气体总压的时候，水就沸腾。我们通常看到水烧开，就是在100摄氏度时水的蒸气压等于一个大气压。蒸气压随温度变化而变化，温度越高，蒸气压越大，当然还和液体种类有关。一定的温度下，与同种物质的液态(或固态)处于平衡状态的蒸气所产生的压强叫饱和蒸气压，它随温度升高而增加。如：放在杯子里的水，会因不断蒸发变得愈来愈少。如果把纯水放在一个密闭的容器里，并抽走上方的空气。当水不断蒸发时，水面上方气相的压力，即水的蒸气所具有的压力就不断增加。但是，当温度一定时，气相压力最终将稳定在一个固定的数值上，这时的气相压力称为水在该温度下的饱和蒸气压力。当气相压力的数值达到饱和蒸气压力的数值时，液相的水分子仍然不断地气化，气相的水分子也不断地冷凝成液体，只是由于水的气化速度等于水蒸气的冷凝速度，液体量才没有减少，气体量也没有增加，液体和气体达到平衡状态。所以，液态纯物质蒸气所具有的压力为其饱和蒸气压力时，气液两相即达到了相平衡。饱和蒸气压是物质的一个重要性质，它的大小取决于物质的本性和温度。饱和蒸气压越大，表示该物质越容易挥

发。 当气液或气固两相平衡时，气相中A物质的气压，就为液相或固相中A物质的饱和蒸气压，简称蒸气压。下面为影响因素： 1.对于放在真空容器中的液体，由于蒸发，液体分子不断进入气相，使气相压力变大，当两相平衡时气相压强就为该液体饱和蒸汽压，其也等于液相的外压；温度升高，液体分子能量更高，更易脱离液体的束缚进入气相，使饱和蒸气压变大。 2.但是一般液体都暴露在空气中，液相外压=蒸气压力+空气压力=101.325KPa），并假设空气不溶于这种液体，一般情况由于外压的增加，蒸气压变大（不过影响比较小） 3.一般讨论的蒸气压都为大量液体的蒸气压，但是当液体变为很小的液滴是，且液滴尺寸越小，由于表面张力而产生附加压力越大，而使蒸气压变高（这也是形成过热液体，过饱和溶液等亚稳态体系的原因）。所以蒸气压与温度，压力，物质特性，在表面化学中液面的曲率也有影响. 不同物质的蒸气压不同，下面总结给出水在不同温度下的饱和蒸气压：
