当一种多组分液体受热时，每一组分的蒸气压将会升高，因而导致总蒸气压升高。
When a multi-component liquid is heated, the vapor pressure of each component will rise, thus causing the total vapor pressure to rise.
当总蒸气压与周围液体的压力相等时，沸腾就发生了，液体变成了气体，遍及液体中的气泡。
When the total vapor pressure reaches the pressure surrounding the liquid, boiling occurs and liquid turns to gas throughout the bulk of the liquid.
拉乌尔定律假定，一种组分按其在混合物中百分比及其纯净物的蒸气压参与形成混合物总蒸气压。
Raoult's law assumes that a component contributes to the total vapor pressure of the mixture in proportion to its percentage of the mixture and its vapor pressure when pure.
