What do you mean by frosting

frosting

When the temperature drops below zero degrees Celsius, the white crystal frost of water vapor in the air near the ground is condensed by dew. Morale and body fluid are born from the ground, while thin cold is frost.

definition

The formation of frost is not only related to the above weather conditions, but also related to the properties of ground objects. Frost is formed on the surface of an object cooled by radiation, so the easier it is to radiate heat and the faster it cools, the easier it is to frost on it. Similar objects, under the same conditions, have the same mass and heat. If they radiate and dissipate heat at the same time at night, objects with large surface area will dissipate more heat, and at the same time, the temperature will drop faster, and it will be easier to frost on them. That is to say, if the surface area of an object is relatively large relative to its mass, it is easy to form frost on it. Grass leaves are very light, but they have a large surface area and are easy to frost on. In addition, the rough surface of an object is more conducive to heat dissipation than the smooth surface, so the rough surface is more prone to frost, such as clods.
