1 answer
The primary cause of the formation of dew on surfaces is the cooling of objects. When the temperature of an object or surface drops below the dew point temperature, water vapor in the air condenses into liquid droplets, creating dew. This cooling can occur through various mechanisms, such as radiation cooling at night or contact with a cooler surface. However, neither the accumulation of dust nor the absorption of sunlight directly cause the formation of dew.
