THE STATES OF MATTER

A solid is the state of matter that has a definite shape and volume.

SOLIDS

The particles are very close together because they have a very strong attraction for each other.

Since they are so close, they cannot move around. So they just vibrate in place.

PROPERTIES OF SOLIDS

There are two types of solids: Crystalline and Amorphous.

TYPES OF SOLIDS

Crystalline Amorphous

Particles in a repeated pattern of rows

Particles have no special arrangement.

Particles don’t move around

Particles don’t move around

Ex: iron, diamond, ice Ex; glass, rubber, wax

Rocks WoodPillowsPeople Pizza

EXAMPLES OF SOLIDS

A liquid is the state of matter that has a definite volume but takes the same shape of its container.

LIQUIDS

The particles move fast enough to overcome the attraction of some particles.

The particles slide past each other.

PROPERTIES OF LIQUIDS

Soda WaterLava JuiceMilk

EXAMPLES OF LIQUIDS

All liquids have surface tension.Surface tension – a force that holds together

particles at the surface of a liquid.ST makes some liquids to form spherical drops (like

water).Liquids have diff erent ST’s than each other.

SURFACE TENSION

EXAMPLES OF SURFACE TENSION

Ex:

Water Rubbing alcohol

VISCOSITY

All liquids have viscosity.Viscosity – a liquid’s resistance to flowThe viscosity of a liquid depends on the attraction

between it’s particles.

Ex: Water has a low viscosity, and that is why we have rivers. Honey has a high viscosity be cause it takes forever to flow.

EXAMPLE OF VISCOSITY

Water Honey

A gas is the state of matter that has no definite shape or volume.

GASES

Particles in a gas move quickly enough they can break away from their attraction for other particles.

The amount of empty space between gas particles can change.

PROPERTIES OF GASES

Helium OxygenNitrogenCarbon dioxideArgon
