frost, hoar, hoarfrost, rime (noun)

ice crystals forming a white deposit (especially on objects outside)

freeze, frost (noun)

weather cold enough to cause freezing

frost, icing (noun)

the formation of frost or ice on a surface

Frost, Robert Frost, Robert Lee Frost (verb)

United States poet famous for his lyrical poems on country life in New England (1874-1963)

frost, ice (verb)

decorate with frosting

"frost a cake"

frost (verb)

provide with a rough or speckled surface or appearance

"frost the glass"; "she frosts her hair"

frost (verb)

cover with frost

"ice crystals frosted the glass"

frost (verb)

damage by frost

"The icy precipitation frosted the flowers and they turned brown"

frost (Noun)

A cover of minute ice crystals on objects that are exposed to the air. Some of these are tree branches, plant stems, leaves, wires, poles, vehicles, rooftops, or aircraft skin. Frost is the same process by which dew is formed except that the temperature of the frosted object is below freezing. Frost can be light or heavy.

frost (Noun)

The cold weather that would cause frost as in (1) to form.

frost (Verb)

To get covered with frost.

frost (Verb)

To coat something (eg a cake) with white icing to resemble frost.

frost (Verb)

To anger or annoy.

Frost

Frost is the solid deposition of water vapor from humid air. It is formed when the temperature of a solid surface is below the freezing point of water and also below the frost point. The size of frost crystals varies depending on the time they have been building up and the amount of water vapour available. Frost crystals are translucent, but scatter light in many directions, so that a coating of frost appears white. There are many types of frost, such as radiation and window frost. Frost may damage crops or reduce future crop yields, hence farmers may take measures to prevent it forming.

Frost

Frost is a thin layer of ice on a solid surface, which forms from water vapor in an above-freezing atmosphere coming in contact with a solid surface whose temperature is below freezing, and resulting in a phase change from water vapor (a gas) to ice (a solid) as the water vapor reaches the freezing point. In temperate climates, it most commonly appears on surfaces near the ground as fragile white crystals; in cold climates, it occurs in a greater variety of forms. The propagation of crystal formation occurs by the process of nucleation. The ice crystals of frost form as the result of fractal process development. The depth of frost crystals varies depending on the amount of time they have been accumulating, and the concentration of the water vapor (humidity). Frost crystals may be invisible (black), clear (translucent), or white; if a mass of frost crystals scatters light in all directions, the coating of frost appears white. Types of frost include crystalline frost (hoar frost or radiation frost) from deposition of water vapor from air of low humidity, white frost in humid conditions, window frost on glass surfaces, advection frost from cold wind over cold surfaces, black frost without visible ice at low temperatures and very low humidity, and rime under supercooled wet conditions.Plants that have evolved in warmer climates suffer damage when the temperature falls low enough to freeze the water in the cells that make up the plant tissue. The tissue damage resulting from this process is known as "frost damage". Farmers in those regions where frost damage is known to affect their crops often invest in substantial means to protect their crops from such damage.
