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:
“Birch boughs enough piled everywhere!
All fresh and sound from the recent ax.
Time someone came with cart and pair
And got them off the wild flowers’ backs.”
—Robert Frost (1874–1963)
“Parents who want a fresh point of view on their furniture are advised to drop down on all fours and accompany the nine or ten month old on his rounds. It is probably many years since you last studied the underside of a dining room chair. The ten month old will study this marvel with as much concentration and reverence as a tourist in the Cathedral of Chartres.”
—Selma H. Fraiberg (20th century)
