States of matter and their properties

States of Matter

There are 4 different

states of matter.

Some substances may exist in more than one state

Example: water

The four states are:

liquid, gas, solid, and plasma

Solids

A solid has a definite

shape and volume.

Solid particles have very

little, if any motion.

There are two types of solids

Crystalline

• particles are arranged in a repeating pattern of rows.

• Ex. Diamond, ice

particles are arranged in a repeating pattern of rows. Ex. Diamond, ice

Amorphous

• particles have no particular order.

• Ex.rubber, wax

Liquid

A liquid has definite volume

but takes the shape of the

container it is in.

Liquid particles have a lot of motion

Properties of Liquids

Viscosity is a liquids

resistance to flow. Honey has a lot

of viscosity, but water has a small amount

of viscosity.

• Surface tension is a force that acts on the particles at the surface of a liquid

• This property allows liquids to form drops

Gas

A gas does not

have definite

shape or volume

Gas particles are very spaced out because they have little attraction between them

Gas particles are in

constant motion

Plasma

Plasma does not have a definite shape or volume.

Example: stars, fire, lightening

The particles in plasma have been separated from one another.

Plasmas can conduct

electricity!
