In a closed condition, the pressure of a vapor in phase equilibrium with a solid or liquid at a certain temperature is called the saturated vapor pressure. The same substance has different saturated vapor pressures at different temperatures and increases with increasing temperature. The saturated vapor pressure of the pure solvent is greater than the saturated vapor pressure of the solution; the saturated vapor pressure of the solid state is less than the saturated vapor pressure of the liquid state for the same substance. Under the conditions of high temperature and obvious temperature difference change, the glass often generates fog, because the surface of the glass contains saturated and supersaturated air at a higher temperature, the glass can not contain the existing water vapor after being rapidly cooled, and the redundant water vapor is condensed into fine dew on the surface of the glass under the action of heterogeneous nucleation, so that the light is subjected to diffuse reflection, and the atomization is opaque.
