Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation. As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets.

When temperatures are low enough, dew takes the form of ice; this form is called frost.

Because dew is related to the temperature of surfaces, in late summer it forms most easily on surfaces that are not warmed by conducted heat from deep ground, such as grass, leaves, railings, car roofs, and bridges.

Dew should not be confused with guttation, which is the process by which plants release excess water from the tips of their leaves.

Definition of "Dew" by Chat GPT: Dew is a type of moisture that forms on surfaces, such as plants or grass, during the night or early morning when the temperature drops and the air is saturated with water vapor. It forms as a result of condensation, where the water vapor in the air turns back into liquid as it comes into contact with a surface that is colder than the surrounding air. Dew is a natural source of water for plants and animals in areas with limited rainfall.
