Phase Changes

Front

What is a phase change?

Back

A phase change is the transformation of a substance from one state of matter to another, such as solid, liquid, or gas.

Front

What are the three main states of matter?

Back

The three main states of matter are solid, liquid, and gas.

Front

What happens to particles during melting?

Back

During melting, particles gain energy and move more freely, transitioning from a solid to a liquid.

Front

What is vaporization?

Back

Vaporization is the phase change from a liquid to a gas.

Front

What is condensation?

Back

Condensation is the phase change from a gas to a liquid.

Front

What is sublimation?

Back

Sublimation is the phase change from a solid directly to a gas without becoming a liquid.

Front

What is deposition?

Back

Deposition is the phase change from a gas directly to a solid without becoming a liquid.

Front

How does temperature affect phase changes?

Back

Temperature affects phase changes by providing or removing energy, which can cause a substance to change from one state to another.

Front

What is the role of energy in phase changes?

Back

Energy is required to be added or removed during phase changes to overcome or establish the forces between particles.

Front

What occurs during freezing?

Back

During freezing, a liquid loses energy and its particles move closer together, forming a solid.
