Matter
Anything that has
a
mass and volume
Particle theory of matter
Matter is made up of particles called
atoms
Particles have
large
spaces between them
Different
substances
are made up of
different
particles
Particles are always
moving
Particles at higher temperatures are moving
faster
than particles at
lower
temperatures
Particles are attracted to one another, the
stronger
the attractive force the
closer
the particles are to each other
States of matter
Solid
Liquid
Gas
Solid
Particles are closely
packed
together
Particles have strong
attractive
forces
Particles can only
vibrate
and
rotate
slowly
Liquid
Particles are
closer
together than in a
gas
Particles have
medium
attractive forces
Particles can
move
around each other in a
medium
way
Gas
Particles are
far apart
from each other
Particles have
weak attractive forces
Particles can
move
around freely and
quickly
The particle theory can be used to describe and
explain
the differences between the three states of
matter
