What does state of matter mean? • Matter= atoms • How much particles move determine their state • Can be: • Solids • Liquids • Gases
Solids • Definite volume • Definite shape • Vibrate but do not move • Only exception: • Ice- particles farther a part than in liquid
Liquid • Definite volume • Not definite shape • Particles attracted to each other, but can move around
Gases • No definite shape • No definite volume • Particles not close to each other and can move around • Space can increase or decrease depending on temperature
Examples of your own • Provide an example, similar to the fish bowl on pg.68-69 of a solid, liquid, and gas • Be prepared to share with class
Particles changing state • Solid to liquid- melting • Liquid to solid (particles slowing down)- freezing • Fill out chart on pg. 70 for other changes
Name that matter • After each statement is read, go to the corner you think represents that type of matter • Can be solid, liquid, gas, or none of these • Can have sharp corners • Does not have mass • Exerts pressure on all sides of container • Has definite volume, but no definite shape • The particles that make this up are completely still • Formed when something melts • Particles vibrate in place • Particles move freely
Put it together • With your group, explain how a hot air balloon works. Think about the states of matter and density.
