化合物的蒸气压指的是这种化合物的气相与其非气相达到平衡状态时的压强。任何物质（包括液态与固态）都有挥发成为气态的趋势，其气态也同样具有凝聚为液态或者凝华为固态的趋势。在给定的温度下，一种物质的气态与其凝聚态（固态或液态）之间会在某一个压强下存在动态平衡。此时单位时间内由气态转变为凝聚态的分子数与由凝聚态转变为气态的分子数相等。这个压强就是此物质在此温度下的饱和蒸气压。蒸气压与物质分子脱离液体或固体的趋势有关。对于液体，从蒸气压高低可以看出蒸发速率的大小。具有较高蒸气压的物质通常说其具有挥发性。

Compounds in the vapor pressure is that compounds in the gas phase with its non-vapor pressure when equilibrium is reached. Any material (including liquid and solid) is a gaseous volatile trend, Huawei also has condensed back to liquid or gel of gaseous solid trend. At a given temperature, the gaseous and condensed a substance (solid or liquid) would exist under a pressure between dynamic balance. Per unit time by the molecules of the gas into condensed and condensed into a equal to the number of gaseous molecules. This pressure is the saturated vapour pressure of the substance at that temperature for. Vapor pressure and trends of material molecule from a liquid or a solid. For the liquid, the size of vapor pressure and low evaporation rate can be seen. Usually said with a higher vapor pressure volatile.

The vapor pressure of the compound refers to its non-gaseous vapor pressures of such compounds in the equilibrium state. Any material (including liquid and solid) has become the trend of volatile gas, which also has gas condensed into a liquid or solid condensate Huawei trend. At a given temperature, there will be at a certain pressure between the gaseous substance and its condensed matter (solid or liquid) homeostasis. In this case the unit of time is the number of molecules transformed from gaseous and condensed matter from the condensed matter into gaseous equal number of molecules. This material is the pressure at this temperature saturated vapor pressure. Vapor pressure and molecular substances from liquid or solid trend related. For liquid, low vapor pressure can be seen from the size of the evaporation rate. Substances with a high vapor pressure often said that it is volatile.

Vapor pressure of the compound is the pressure of the gas phase of the compound and the gas phase to the equilibrium state. Any substance (including liquid and solid) has become the trend of the volatile gas, gas also has condensed into liquid or solid sublimation for the trend. At a given temperature, a substance's gas and its condensed state (solid or liquid) will be in a dynamic equilibrium under a certain pressure. The number of molecules in a unit time changed from a gas to a condensed state is equal to the number of molecules in the condensed state. This pressure is the saturation vapor pressure of the substance at this temperature. Vapor pressure is related to the tendency of the material molecules to escape from the liquid or solid. For liquids, the evaporation rate can be seen from the vapor pressure. A substance with a higher vapor pressure is generally said to have a volatile.
