Phase Changes in Matter

Emily from the University of Memphis explains phase changes between solids, liquids, and gases. The video covers melting, freezing, evaporation, condensation, sublimation, and deposition, providing examples and scientific terms for each process. The video concludes with a review of the concepts discussed.

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

• Water boiling

• Dry ice sublimating

What happens to the molecules of a liquid during evaporation?

• They speed up and spread further apart

• They slow down and come closer together

• They form a solid

• They stop moving

Which process involves a liquid turning into a gas due to heat?
