Questions

States of MatterLesson 1

●     Solid●     Crystalline solid●     Amorphous solid●     Liquid●     Fluid●     Surface tension●     Viscosity●     Gas●     Pressure

●     What are the different properties (and particle behavior) of solids, liquids, and gases? What are their significance and how do they influence the behavior of these different states of matter?

Changes in StateLesson 2

●     Melting●     Melting point●     Freezing●     Vaporization●     Evaporation●     Boiling●     Boiling point●     Condensation●     Sublimation

●     What are the changes in state that a solid, liquid, or gas can undergo? When do those changes take place? What happens to particles during these changes?

Gas BehaviorLesson 3

●     Charles’s Law●     Directly proportional●     Boyle’s Law●     Inversely proportional●     Guy Lussac’s Law

●     What are the three factors that influence gas behavior? How are they related? Which laws govern these factors? What does this relationship look like on a coordinate plane (a graph)?
