Question

question 5
ch 6 water and atmospheric moisture: humidity
which of the following has occurred when a cold glass of water forms condensation?
the frost point temperature has been met for air surrounding the glass
sublimation is occurring
the dew point temperature has been met for air surrounding the glass

Explanation:

When the temperature of the air surrounding the cold glass reaches the dew - point temperature, the air becomes saturated with water vapor. At this point, the water vapor in the air condenses on the cold surface of the glass. Frost - point temperature is related to the formation of frost (when water vapor deposits directly as ice, which is not the case here as condensation is liquid water formation). Sublimation is the process of a solid turning directly into a gas (opposite of deposition) and is not relevant to condensation.

Answer:

The dew point temperature has been met for air surrounding the glass.
