States of Matter

Solid, Liquid, Gas, and Plasma

Well-Known States of Matter

• Solid• Ice, chairs, tables, ect

• Liquid• Liquid water, milk, juice, ect

• Gas• Water vapor, oxygen, hydrogen, ect

Solid• Solid is a state of matter in which the

molecules are compact and close together, with very little movement.

• Solids have a definite shape and a definite volume.

Liquid• Liquid is a state of matter in which

the molecules are a little further apart, allowing for more movement (which is why liquids can change shape).

• Liquids have a definite volume but they take on the shape of their container.

Gas• Gas is a state of matter in which

the molecules are so far apart, there is a lot of movement.

• Gases have no definite shape or volume.
