1 SECTION 12.1 The Properties of Gases

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)

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