1. The Properties of Gases
Section 12.1

2. After reading Section 12.1, you should know:
The properties of a gas
How the kinetic theory relates to the Kelvin temperature

3. Properties of Gases (Review of the Kinetic Theory)
Compressibility
How much the volume of matter decreases when it is under pressure
Gases have a high compressibility
No attractive or repulsive forces exist between gas particles
Gases are free to move inside their containers
Gases will expand until it takes the shape and volume of a container
Gas particles are in constant motion
Move in straight paths
Collisions are perfectly elastic

4. Variables that Describe a Gas
Pressure
Measured in kilopascals (kPa)
Amount of gas
Measured in moles (n)
Volume
Measured in liters (L)
Temperature
Measured in Kelvin (K)
