平衡蒸汽压表格
Vapour pressure 蒸汽压
Vapor pressure is the pressure of a vapor in equilibrium with its non-vapor phases. 蒸汽压,是一个与非气相平衡的蒸汽压力。
All solids and liquids have a tendency to evaporate to a gaseous form, and all gases have a tendency to condense back. 所有的固体和液体,都有一个要蒸发成气态的倾向。所有的气体,都有一个要凝固成固态的倾向。
At any given temperature, for a particular substance, there is a partial pressure at which the gas of that substance is in dynamic equilibrium with its liquid or solid forms. This is the vapor pressure of that substance at that temperature. 在一个一定的温度下,对于一个特定的物质,在一个分压下此物质的气态和其液态或者固态达到平衡。这就是这个物质在此温度下的蒸汽压。
