…When the surface temperature of a flat object exposed to air is lowered, the temperature at which the water vapor in the air condenses (or sublimates) and begins to form dew (or frost) on the surface of the object is called the dew point or dew point temperature. (The point at which frost forms is sometimes called the frost point or frost point temperature.) This is the temperature at which the vapor pressure in the air becomes equal to the saturated vapor pressure. … *Some of the terminology that mentions "frost-point" is listed below.
