Solids Solid: is the state of matter that has a
definite shape and volume. The particles have a strong attraction
for each other; this is why the particles are close together.

Molecules in a Solid The molecules in a solid move, but since
they are so close together they just vibrate against each other.

Two Types of SolidsCrystalline Amorphous
• Particles in a orderly, repeating pattern of rows
• Particles have no special arrangement.
• Particles don’t move around, but vibrate.
• Particles don’t move around, but vibrate.
• Ex: iron, diamond, ice • Ex: glass, rubber, wax

Liquids Liquid: is the state of matter that has a
definite volume but takes on the shape of its container.

Molecules in a Liquid The molecules in a liquid move fast
enough to over come some the attraction between other molecules.
The molecules can move freely within their definite volume.

Properties of a Liquid Viscosity: a liquid’s resistance to flow.

Examples of Viscosity Water has a low viscosity because we
have rivers. Syrup has a higher viscosity because
when you squeeze it out of the bottle, it takes a little while to come out.

Properties of a Liquid (cont.) Surface Tension: a force that holds
together particles at the surface of a liquid.

Examples of Surface Tension If you drip water on to wax paper using
a eye dropper, you can see the drops rise off the paper quite clearly.
If you do the same technique above but use rubbing alcohol, the bubbles are very low to the table.
High Surface Tension Low Surface Tension

Gases Gas: is the state of matter that has no
definite shape or volume.

Molecules in a Gas The molecules in a gas can move
quickly and freely. The amount of empty space between
the molecules can change
