Back

A liquid is a state of matter where particles are close together but can move freely, taking the shape of their container.

Front

What is a gas?

A gas is a state of matter where particles are far apart and move freely, filling the entire volume of their container.

Front

What happens during melting?

Back

During melting, a solid turns into a liquid as it gains heat energy.

Front

What happens during freezing?

Back

During freezing, a liquid turns into a solid as it loses heat energy.
