Solids, Liquids and Gases

Materials are:based on solids, liquids

or gases bases on there shapes

and volumes

Solids

Definite shape and volumeCannot be compressed into a

smaller volumeDoes not assume the shape of

container it is in

Liquids

No definite shape but has a definite volume

Cannot be compressed into a smaller volume

Assumes the shape of container it is in

Gas

No definite shape and no definite volume

Can be compressed into a smaller volume

Assumes the shape of container it is in

Plasma and BECAlthough rare on earth plasma

makes over ninety percent of matter in the universe –(super hot)

Bose-Einstein Condensate- Predicted by Einstein –(super cold)

Kinetic Theory

Kinetic means to move

Kinetic energy is the energy of motion

The kinetic theory states that all particles of matter are in constant motion

Kinetic Theory

Behavior of Gases Free moving particlesAlthough all particles of

matter have forces of attraction- particles in gasses move so fast these attractive forces have no effect

Kinetic Theory of GasesThe constant motion of particles in a gas compels a gas to fill a container of any shape or size.

Particle of gas are in constant random motion

Motion is only affected by collision

Force of attraction can be ignored

Behaviors of liquids A liquid takes the shape of its

container because particles in a liquid can flow to new locations.

The volume of a liquid is constant because the forces of attraction keep particles of a liquid close together

Behaviors of Solids

Solid have a definite shape and volume because the particles only vibrate around fixed locations which limit it’s motion.
