Dew

Dew is the term for small droplets of water that appear on thin objects in the morning. Dew results from atmospheric moisture that condenses after a warm day and appears during the night on cooled surfaces as small drops. The cool surfaces cool the nearby air, decreasing the amount of humidity (dissolved moisture) the local air can hold. The extra vapor condenses (precipitates out of solution in the air). When temperatures are low enough, dew will take the form of ice; this form is called frost.
