Front

How do particles behave in a solid?

Back

Particles vibrate in place and do not change relative positions.

How do particles behave in a gas?

Back

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

Front

What is density?

Back

Density is the mass of an object divided by its volume.

Front

What happens to the particles of water when it freezes?

Back

The particles slow down and arrange themselves in a fixed position, forming a solid.

Front

What happens to the particles of water when it boils?

Back

The particles gain energy, move faster, and change from liquid to gas.
