Explain how dew, frozen dew, and visible frost form
What will be an ideal response?
ANSWER: Dew forms when the air cools to the dew point, the temperature at which saturation occurs. Frozen dew forms if the air temperature drops to freezing or below. The dew will freeze, becoming tiny beads of ice. Visible frost forms on cold, clear, calm mornings when the dew-point temperature is at or below freezing. When the air temperature cools to the dew point (now called the frost point) and further cooling occurs, water vapor can change directly to ice without becoming a liquid first—a process called deposition.?
