Nature of Matter

Particles of all matter are in constant random motion.

• True
• False

The particles of gases are free to move.

• True

• False

In this state of matter, particles are tightly packed and cannot move.

• gas

• solid

• liquid

The particles of solids ________________

• vibrate about their fixed postions

• are able to slide over each other

• move about freely at high speeds and in random direction

• do not move

The particles of liquids ________________

• vibrate about their fixed postions

• are able to slide over each other

• move about freely at high speeds and in random direction

• do not move

The particles of gases ________________

• vibrate about their fixed postions

• are able to slide over each other

• move about freely at high speeds and in random direction

• do not move

These particles are held together by very strong forces of attraction

• Solid

• Liquid

• Gas

• Plasma

What happens to particles of liquid when they are heated?

• They slide over one another faster and move further apart

• They slow down and compress

• They stop moving

• They slide over one another slower and move closer together
