Amplify Phase Change Assessment Review

Front

What happens to a liquid with weaker molecular attractions when energy is added?

Back

It changes phase more easily.

Front

What phase change occurs when molecules move from a liquid state to moving freely in all directions?

Back

Liquid to gas.

Front

What does it suggest if a liquid turns into a solid when energy is removed?

Back

It has stronger molecular attractions than other liquids.

Front

What does a higher freezing point indicate about a substance's molecular attractions?

Back

It suggests stronger molecular attractions.

Front

What property of ice remains unchanged during melting?

Back

The molecular attraction between its molecules.

Front

Define phase change.

Back

A transition of a substance from one state of matter to another, such as solid, liquid, or gas.

Front

What is kinetic energy in the context of molecular movement?

Back

The energy that molecules possess due to their motion.

Front

How does temperature affect molecular movement in liquids?

Back

Higher temperatures increase molecular movement, while lower temperatures decrease it.

Front

What is the relationship between molecular attraction and freezing point?

Back

Stronger molecular attractions typically result in higher freezing points.

Front

What occurs during the process of freezing?

Back

Molecules lose energy and move closer together to form a solid.
