1. State of Matter Volume Shape Structure/Energy
constant OR changing to volume of container?
Shape
constant or changing to shape of container?
Structure/Energy
How close together are the molecules and how much energy to they have?
Solid
Liquid
Gas

2. Behavior of Gases
Volume, Temperature and Pressure affect the behavior of gases!!
Volume- the amount of space of the gas container
Temperature- average kinetic energy (movement) of particles
Pressure- collisions of tiny gas particles
More collisions= higher pressure
Less collisions= lower pressure

3. Inverse Relationship- V & P
Increase pressure
Decrease pressure
Increase volume
Decrease volume
WITHOUT CHANGING THE AMOUNT OF GAS MOLECULES in the container--SAME AMOUNT OF GAS!!

4. Direct Relationship- V & T
Increase volume
Increase temperature
Decrease Temperature
Decrease volume

5. Direct Relationship- P & T
decrease pressure
increase pressure
decrease temperature
increase temperature

6. Remove gas
Decrease pressure
Add gas
Increase pressure

7. Physical Properties of Gases
Gases have no definite shape or volume
Gases are compressible
Gases have low density
Gases spontaneously diffuse
Gases exert uniform pressure on the walls of the container

8. Can Crushing
What variables are causing the can to crush?
In your notes: Make observations!!
Write a description and
draw diagrams
to explain what happens.
1. Put small amount of water in a clean soda can.
2. Heat the water in the can on the hot plate until you see steam coming from the can.
3. IMMEDIATELY, use tongs to turn the can upside down into a tub of ice water.
