Cambios físicos: evaporación y condensación

The video tutorial explains the processes of evaporation and condensation. It describes how water changes from a liquid to a gas, known as water vapor, through evaporation. The tutorial also covers condensation, where water vapor cools and becomes liquid, forming moisture and clouds. These processes are examples of physical changes in matter.

What happens to water in a glass over time when it is left out?

• It becomes a solid.

• It remains unchanged.

• It evaporates into the air.

• It turns into ice.

What is the process called when a gas turns into a liquid?

• Condensation

• Evaporation

• Sublimation

• Freezing

Why does the outside of a cold glass become wet on a humid day?

• The glass absorbs moisture from the table.

• Water vapor in the air condenses on the glass.

• The glass is sweating.

• The glass is leaking.

How do clouds form in the atmosphere?

• Through the evaporation of water.

• By the melting of ice.

• By the condensation of water vapor into droplets.

• Through the solidification of gases.

Which of the following is an example of a physical change?

• Burning wood

• Cooking an egg

• Rusting iron

• Evaporation of water
