Condensation and Dew Formation Concepts

The video explains the process of condensation, where water vapors touch a cool surface and form water droplets. It uses the example of morning dew on grass to illustrate how condensation occurs when air full of water vapors comes into contact with cooler grass leaves, resulting in water drops appearing on the grass.

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

• They evaporate

• They freeze

• They disperse

• They condense

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

• Evaporation

• Precipitation

• Condensation

• Sublimation

Why is the grass wet in the morning?

• The grass was watered

• The grass absorbed moisture from the soil

• Dew formed due to condensation

• It rained overnight

What condition is necessary for dew drops to form on grass?

• The grass must be warmer than the air

• The grass must be in direct sunlight

• The air must be dry

• The grass must be cooler than the air

What happens to water in the air when it touches cooler grass leaves?

• It remains as vapor

• It freezes

• It condenses into water drops

• It evaporates
