Understanding Phase Changes

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

• Condensation

• Evaporation

• Vaporization

• Sublimation

Name the phase change that occurs when a solid becomes a gas without becoming a liquid first.

• Sublimation

• Melting

• Condensation

• Evaporation

What do we call the change from a liquid to a solid?

• Condensation

• Evaporation

• Melting

• Freezing

Describe what happens to water when it evaporates.

• Water turns into solid crystals when evaporating.

• Water remains a liquid and does not change state.

• Water freezes into ice during evaporation.

• Water changes from liquid to gas during evaporation.

What is the term for the change from a solid to a liquid?

• Condensation

• Sublimation

• Freezing

• Melting

Which of these materials can stretch??

• Glass

• Rubber

• Metal

What happens to the temperature of a liquid during evaporation?

• The temperature of the liquid remains constant during evaporation.

• The temperature of the liquid increases during evaporation.

• The temperature of the liquid decreases during evaporation.

• The temperature of the liquid fluctuates randomly during evaporation.

What happens to ice when it gets warm?

• It turns into water

• It disappears

• It becomes a gas

How does temperature affect the evaporation process?

• Higher temperatures increase the rate of evaporation.

• Lower temperatures decrease the rate of evaporation.

• Evaporation occurs faster at lower altitudes.

• Temperature has no effect on evaporation rates.

If you leave a piece of bread out, what happens to it over time?

• It gets fresher

• It becomes hard and moldy

• It stays the same
