AIM: How does matter change phases? OBJECTIVES Identify the five ways in which matter can change from one phase to another
AIM: How does matter change phase? Vocabulary Condensation, evaporation, freezing, melting, sublimation
Note: Holt O/H #206 Solid liquid gas
Note: Holt O/H #206 Solid liquid gas Describe the molecules of the solid!
Note: Holt O/H #206 Solid liquid gas Describe the molecules of the liquid!
Note: Holt O/H #206 Solid liquid gas Describe the molecules of the gas!
SOLIDS: Definite Shape and Volume have less energy the particle vibrate --- but are very close together
LIQUIDS: Definite Volume. But takes the shape of its container have a little more kinetic energy than solids
GAS: Has NEITHER a Definite Shape nor a Definite Volume have the most kinetic energy
The Kinetic energy of a molecule: Which type of molecule has the most kinetic energy? (solid, liquid, or gas) Which type of molecule has the least kinetic energy?
What happens to the molecules of the solid? How would you describe its kinetic energy? What happens when you add heat energy to a solid?
The solid turns into a liquid That is called melting! What phase change happens when you add heat energy to a solid?
What happens to the molecules of the liquid? How would you describe its change in kinetic energy? What happens when you add heat energy to a liquid?
The liquid turns into a gas? This is called evaporation What PHASE change happens when you add heat energy to a liquid?
The liquid turns to a solid. The kinetic energy slows down The particles get closer together Can you really do that?
I C E The phase change is called freezing!
The gas turns into a liquid How would you describe the change in Kinetic Energy? How would you describe the change in vibration of the molecules?
The gas turns into a liquid This is called condensation!
