Extended data:

The reason why the window is foggy:

1. Under the condition of constant air humidity, when the temperature of the window is lower than the dew point temperature, dew will form on the surface of the window, which is the phenomenon of fogging on the front windshield that we often see.

There is a certain temperature difference between the two sides of the window. When the saturated vapor pressure of surface moisture at lower temperature is lower than the surrounding environment, water vapor will gather on the glass surface and dialyze out in the form of tiny water droplets to form fog vapor.

3. If the dew point temperature is higher than zero degrees Celsius, it will fog; If the dew point temperature is below zero degrees Celsius, frost will form.
