I WONDER - Is Frost Different To Dew?

The video tutorial explains the differences between dew and frost formation. Dew forms when the air is cool but above freezing, causing moisture to condense on surfaces. Frost forms when the temperature is below freezing, and water vapor turns directly into ice crystals through sublimation.

What is the main difference in appearance between dew and frost?

• Dew is liquid, frost is solid.

• Dew is solid, frost is liquid.

• Dew is colder than frost.

• Dew and frost have the same appearance.

Under what conditions does dew form?

• When the air is below freezing.

• When the air is cool but above freezing.

• When the air is hot and dry.

• When there is no moisture in the air.

What happens to moisture in the air to form dew?

• It turns into ice crystals.

• It condenses on surfaces.

• It freezes.

• It evaporates.

How does frost form?

• By condensation of moisture on surfaces.

• By sublimation of water vapor into ice crystals.

• By melting of ice.

• By evaporation of water.

What is the process called when water vapor turns directly into ice crystals?

• Freezing

• Evaporation

• Condensation

• Sublimation
