Is the frost solidified or coagulated?

Frost is when the water vapor on the ground meets the temperature below zero degrees Celsius, which changes from gas to solid and condenses into ice crystals on the ground or grass leaves. When the temperature and air pressure are lower than the triple point, condensation is a state change of matter.

. In the process of sublimation, matter will release heat.

The conditions of condensation formation are special, which require the concentration of gas to meet certain requirements and the temperature to be lower than freezing point, such as water vapor below 0 degrees Celsius. First frost is different from first frost and Chushuang. They are three different concepts. "Frost" refers to a white ice crystal formed by condensation of water vapor on the ground in cold weather; "Frost" refers to one of the most common agrometeorological disasters. The "first frost" solar term refers to the season that reflects the sudden drop of temperature, while the "first frost" does not mean "frosting", but represents the cold weather.
