Dew Formation and Condensation Concepts

The video introduces the MakeMeGenius website, which offers free science videos. It explains the process of condensation, where water vapor becomes liquid upon touching a cool surface. The video demonstrates how dew forms on grass when the air is full of water vapor and the grass is cooler than the air. Additional resources, including PowerPoint presentations for children, are available on the website.

What happens to water vapors when they come into contact with a cool surface?

• They evaporate.

• They become dense and form condensation.

• They freeze immediately.

• They disappear.

What is the primary reason dew forms on grass in the morning?

• The air is full of water vapors and the grass is cooler than the air.

• The grass releases water at night.

• The grass absorbs water from the soil.

• The grass is heated by the sun.

Which of the following is NOT a condition for dew formation?

• Water vapors must condense on the grass.

• Grass must be cooler than the air.

• Grass must be warmer than the air.

• Air must be full of water vapors.

What is the process called when water vapors turn into liquid on a cool surface?

• Precipitation

• Condensation

• Sublimation

• Evaporation
