Can winter frost form words?
The formation of frost is not only related to the weather conditions at that time, but also related to the nature of attached objects. When the surface temperature of the object is very low, but the air temperature near the surface of the object is relatively high, there is a temperature difference between the air and the surface of the object. If the temperature difference between the surface of the object and the air is mainly caused by the radiation cooling of the surface of the object.
When hot air touches the surface of a cold object, the air will cool down, and when the water vapor is supersaturated, excess water vapor will be precipitated. If the temperature is lower than 0℃, the excess water vapor condenses into ice crystals on the surface of the object, which is frost. Therefore, frost is always formed under weather conditions that are conducive to radiation cooling on the surface of objects.
Frost reason: Water vapor in the air condenses directly when it is cold. In winter nights, when the ground temperature drops below 0℃, the water vapor in the air will quickly condense on the ground, forming small solid crystals, that is, the frost will directly change from liquid water to solid crystals-condensation.
