•What is Mass?•Mass- measure of the amount of matter

•What is Matter?•Matter- anything that has mass and takes up space (volume)

•What is Volume?•Volume- the amount of space an object takes up

•What is an atom?•Atom- smallest unit of an element that maintains the chemical identity of that element

•What is an element?•Element- a pure substance that cannot be broken down into simpler, stable substances and is made of one type of atom

•What is a compound?•Compound- a substance that can be broken down into simple stable substances •Two or more atoms chemically bonded together

•Extensive Property- depends on the amount of matter present•Volume, mass, energy

•Intensive Property- does not depend on the amount of matter present•Melting/boiling point, density, conductivity

•Solid- definite volume Solid- definite volume and shapeand shape•Strong forces, vibrating particles
