SOLIDS Definite Shape No Definite Volume Particles: Very close together

TYPES OF SOLIDS: Crystalline Solids -Particles form a regular

repeating pattern, mostly made up of Crystals.

Amorphous Solids -Particles not arranged in a regular

pattern, plastic, rubbers, glass.

LIQUIDS Definite Volume No Definite Shape Particles are packed together, but more freely.

Fluid= “A Substance that flows.”

PROPERTIES OF A LIQUID Surface Tension: Result on an inward pull of molecules belonging to a liquid that brings the molecules on the surface more together.

Viscosity: The liquid’s resistance to flow.

GASES A gas is a fluid. No definite shape No definite volume Particles are spread apart

MELTING Melting is the change of a solid to liquid.

Occurs at a specific melting point called melting point. At its melting point the particles of a solid substance are vibrating so fast that they break free from their fixed positions.

FREEZING The state from a liquid to a solid is

called freezing. This process is the reverse of melting . At the freezing temperature the particles of a liquid are moving so slowly that they begin to form regular patterns.

VAPORIZATION Vaporization takes place when the

particles in a liquid gain enough energy to form a gas.

BOILING Another kind of vaporization is called

boiling occurs when a liquid changes to a gas below its surface as well as at the surface the results can be seen when the boiling liquid bubbles

CONDENSATION This is the opposite of vaporization this

occurs when particles in a gas loose enough thermal energy to form a liquid.

SUBLIMATION Occurs when the surface particles of a

solid gain enough energy that they form a gas. During sublimation particles of a solid do not pass through a liquid state as they form a gas.
