Materials: Properties Big Picture questions: What are the differences between the states of matter; solids, liquids and gases? What are some common examples of the states of matter? Common Misconceptions: Materials always stay in 1 specific state. Ice, water and steam are all different materials/compounds. Atom, compound and particle refer to the same thing.
