'''液体'''是三大物质形态之一。它没有确定的形状,往往受容器的影响。但它的[[体积]]在[[压力]]及[[温度]]不变的环境下,是固定不变的。液体[[分子]]间的距离较远,分子运动也较剧烈,分子间的吸引力较小。增温或减压一般能使液体汽化,成为[[气体]]。

液体是三大物质形态之一。它是没有确定的形状,往往受容器影响。容器是什么形状,注入液体,液体就呈什么形状。但它的体积在[[压力]]及[[温度]]不变的环境下,是固定不变的。此外,液体对容器的边施加压力和其他物态一样。这压力传送往四面八方,不但没有减小并且与深度一起增加(这就是水越深,水压越大的原因)。 <ref>[http://www.258.com/news/1508526866.html 液体的基本特性是什么?与压力温度有什么关系?],互联网服务平台网,2018-05-29</ref>

液体的蒸气压随[[温度]]的升高而增大,当液体的蒸气压等于外界[[大气压]]时,液体内部产生大量气泡并不断逸出,在液体内部和表面同时发生剧烈[[汽化]]的现象。这种现象称为沸腾,此时的温度称为该液体的[[沸点]]。以水为例,一个大气压下,若水温达到100℃,此时水的蒸气压正好是1个大气压,水开始沸腾,100℃即是1个大气压下水的沸点。
