Nature of Matter

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

Why does the mass of matter not change during expansion or contraction?

• The number of particles remains the same

• The number of particles change

A table is made up of matter because,

• It has mass

• It occupies space

• It has some mass and occupies space

• Floats on water
