AIM: How does matter change phases?
Identify the five ways in which matter can change from one phase to another
AIM: How does matter change phase?
Condensation, evaporation, freezing, melting, sublimation
Note: Holt O/H #206
Solid liquid gas
Note: Holt O/H #206
Describe the molecules of the solid!
Solid liquid gas
Note: Holt O/H #206
Describe the molecules of the liquid!
Solid liquid gas
Note: Holt O/H #206
Describe the molecules of the gas!
Solid liquid 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 when you add heat energy to a solid?
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 when you add heat energy to a liquid?
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?
What happens if you remove the energy from the 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!
What happens if you remove the energy from the gas?
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!
