Amplify Phase Change Review

Front

What is a gas?

Back

A gas has no visible shape because its molecules can move away from each other.

Front

How do the molecules in a liquid behave?

Back

Molecules in a liquid move around each other.

Front

What is a phase change?

Back

A phase change occurs when the molecules of a substance experience a change in their freedom of movement.

Front

What describes a solid?

Back

In a solid, molecules vibrate while clumped together with no freedom to move about.

Front

What describes a liquid?

Back

In a liquid, molecules can move around each other but not away from each other, and it changes shape with its container.

Front

What happens to molecules during melting?

Back

During melting, solid molecules gain energy and begin to move more freely, transitioning into a liquid.

Front

What happens to molecules during freezing?

Back

During freezing, liquid molecules lose energy and become more tightly packed, transitioning into a solid.

Front

What is evaporation?

Back

Evaporation is the process where liquid molecules gain enough energy to escape into the gas phase.

Front

What is condensation?

Back

Condensation is the process where gas molecules lose energy and transition back into the liquid phase.

Front

What is sublimation?

Back

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