Phase Change Flashcard Review

Front

What is deposition?

Back

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

Front

What happens to thermal energy when a gas changes to a liquid?

Back

Thermal energy (heat) must be removed when a gas changes to a liquid.

Front

What is solidification?

Back

Solidification, also known as freezing, is the process where a liquid turns into a solid.

Front

How are particles arranged in a liquid?

Back

In a liquid, particles are close together but can move past one another, allowing the liquid to flow.

Front

What occurs when a gas turns into a liquid?

Back

When a gas turns into a liquid, the particles move closer together and slow down.

Front

What is evaporation?

Back

Evaporation is the process where a liquid turns into a gas, usually at the surface of the liquid.

Front

What is condensation?

Back

Condensation is the phase change where a gas turns into a liquid, typically when it cools.

Front

What is sublimation?

Back

Sublimation is the process where a solid turns directly into a gas without becoming a liquid first.

Front

What is melting?

Back

Melting is the phase change where a solid turns into a liquid when heat is added.

Front

What is the role of thermal energy in phase changes?

Back

Thermal energy is the heat energy that is either added or removed during phase changes, affecting the state of matter.
