What do solid particles look like?

Back

Solid particles are closely packed together and vibrate in place.

Front

What do liquid particles look like?

Back

Liquid particles are close together but can move past each other, allowing liquids to flow.

Front

What do gas particles look like?

Back

Gas particles are far apart and move freely, filling the space available.

Front

What happens to water when it freezes?

Back

Water changes from a liquid to a solid when the temperature drops below 0 degrees Celsius.
