molecule =the smallest particle of a compound that still has the properties of a compound
atom =the smallest part of an element that still has the properties of an element
solid = a substance that has definite shape or volume
atomic theroy = the idea that everything is made up of small particles
liquid = a substance that has a definite volume but no definite shape
compound = a type of matter made up of two or more elements
gas = a substance without a definite volume or shape
mixture = different materials placed together but each material has its own properties
solution = a mixture in which substances are spread out evenly but will not settle

Science Chapter 4 Vocabulary
physical change = a change in some properties without forming a different kind of matter
volume = the amount of space an object takes up
melting = the change of a solid into a liquid
mass = the amount of matter in solid, liquid, or gas
freezing = the change of a liquid into a solid
weight = the force of Earth's pull on an object
chemical change = the change of one or more types of matterinto other types of matter with different properties
law conservation of mass = a rule stating that in chemical change,mass is not created or destroyed; it only changes from one form to another
