THE PARTICLE MODEL FOR MATTER:

Explains why matter has different properties in different states

PARTICLE = an atom, the smallest piece of matter

MODEL= a representation

MATTER = anything that has a mass and a volume

** Mass is the amount of matter in an object

** Volume is how much space an object takes up

THE PARTICLE MODEL FOR MATTER STATES THAT ALL MATTER IS MADE UP OF TINY MOVING PARTICLES CALLED ATOMS

STATES OF MATTER

Solid:Atoms are close together.

Has a definite shape and volume

** think of the inside of a classroom

STATES OF MATTER

Liquid:Atoms have some space between them.

Has a definite volume but not a definite shape

**think of the hallway during passing

STATES OF MATTER

Gas:

Atoms have a lot of space between them.

Does not have a definite shape or volume

** think of when you leave the building
