Evaporation

The video explains how molecules with higher energy evaporate from a liquid to a gas, highlighting the differences between evaporation and boiling. It discusses evaporation's role in the water cycle, driven by solar energy, and how water vapor eventually condenses to form clouds.

What is the main difference between evaporation and boiling?

• Evaporation occurs at a specific temperature.

• Boiling involves only surface molecules.

• Evaporation happens over a range of temperatures.

• Boiling is driven by solar energy.

Where does evaporation primarily occur?

• At the surface of the liquid

• Throughout the liquid

• At the bottom of the liquid

• In the air above the liquid

Which process is an essential part of the water cycle?

• Condensation

• Sublimation

• Precipitation

• Evaporation

What drives the evaporation of water from oceans and lakes?

• Wind energy

• Solar energy

• Tidal energy

• Geothermal energy

What eventually happens to water vapor in the atmosphere?

• It evaporates further

• It condenses to form clouds

• It forms rainbows

• It turns into ice
