What happens to the molecules in a substance when energy is transferred out of it?

Back

The molecules slow down and can cause a phase change, potentially turning into a solid.

Front

What is 'Freedom of Movement' in the context of molecular behavior?

Back

It refers to the way molecules in a substance move around relative to each other.

Front

Which state of matter has molecules that slide past each other but stay close together?

Back

Liquid.

Front

How do the molecules in a gas behave?

Back

They move away from each other.

Front

In a solid, how do the particles behave?

Back

They vibrate in place.

Front

What is a phase change?

Back

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

Front

What is kinetic energy?

Back

The energy that an object possesses due to its motion, which affects how molecules move.

Front

What is the difference between a solid and a liquid in terms of molecular arrangement?

Back

In solids, molecules are tightly packed and vibrate in place; in liquids, molecules are close but can slide past each other.

Front

What occurs during melting?

Back

A solid absorbs energy and its molecules gain enough kinetic energy to break free from their fixed positions.

Front

What occurs during freezing?

Back

A liquid loses energy, causing its molecules to slow down and arrange into a solid structure.
