• Solid

• Liquid

• Gas

• Shape

What is the kinetic theory of matter?

• all matter is made of particles which are in constant motion

• all matter is made of particles that are moving at the same speed, regardless the state

• particles in matter are only in motion when they are changing states

• particle motion depends on the the type of matter and the state it is in

Has a definite shape and volume

• solid

• liquid

• gas

Particles are tightly packed

• solid

• liquid

• gas

Have a definite volume, but no definite shape

• liquid

• solid

• gas

Particles are tightly packed, but far enough apart to slide over one another
