what are the three states of matter?

what is the Kinetic Theory of Matter

• Matter is made up of particles which are in continual random motion.

• Matter is made up of waves which are in continual random motion.

• explain how changes in energy content affect the state of matter

what is not a characteristic of a solid

• the solid takes up the same amount of space

• can be very hard and brittle

• they are in a fixed position

• indefinite shape and a definite volume

which is not a characteristic of a liquid

• are tightly packed

• liquid particles have enough energy to be able to move past each other readily, which allows liquids to flow

• indefinite shape and a definite volume

• very far apart and move freely

what is not a characteristic of a gas

• very far apart and move freely

• move almost independently of one another

• fill whatever container they are in

• tightly packed shape
