The frost point is similar to the dew point, in that it is the temperature to which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to be deposited on a surface as ice without going through the liquid phase. (Compare with sublimation.) The frost point for a given parcel of air is always higher than the dew point, as the stronger bonding between water molecules on the surface of ice requires higher temperature to break.

Famous quotes containing the words frost and/or point:
“The shattered water made a misty din.
Great waves looked over others coming in,
And thought of doing something to the shore
That water never did to land before.”
—Robert Frost (1874–1963)
“What’s the point of fighting the dollars
when all you need is a warm bed?
When the dog barks you let him in.
All we need is someone to let us in.
And one other thing:
to consider the lilies in the field.”
—Anne Sexton (1928–1974)
