Question

explain the process that causes dew to form on blades of grass.

Explanation:

At night, the temperature drops. The warm - moist air near the ground cools down when it comes in contact with the cold blades of grass. As the air cools, its capacity to hold water vapor decreases. When the air reaches its dew - point temperature, the water vapor in the air condenses into liquid water droplets, which form dew on the blades of grass. This is a process of condensation.

Answer:

Dew forms on blades of grass through the process of condensation. At night, the air near the ground cools when it touches the cold grass. As the air cools to its dew - point temperature, water vapor in the air changes from a gas to a liquid, creating dew droplets on the grass.
