What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, forming droplets.

Front

What is sublimation?

Back

Sublimation is the phase change in which a solid turns directly into a gas without passing through the liquid state.

Front

What is evaporation?

Back

Evaporation is the process by which a liquid turns into a gas, typically occurring at the surface of the liquid.

Front

What is freezing?

Back

Freezing is the phase change in which a liquid turns into a solid as it loses heat.

Front

What is melting?

Back

Melting is the process by which a solid turns into a liquid when it absorbs heat.

Front

What is deposition?

Back

Deposition is the phase change in which a gas turns directly into a solid without becoming a liquid first.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at the surface of a liquid at any temperature, while boiling occurs throughout the liquid at a specific temperature.

Front

What is the role of temperature in phase changes?

Back

Temperature affects the energy of particles; higher temperatures can lead to melting and evaporation, while lower temperatures can lead to freezing and condensation.

Front

What happens to the particles during condensation?

Back

During condensation, particles lose energy and come closer together, forming liquid.

Front

What is an example of sublimation?

Back

An example of sublimation is dry ice (solid carbon dioxide) turning directly into carbon dioxide gas.
