Chapter 8 Gases Practice Problems Section 8.1 Properties ...
Chapter 8 – Gases – Practice Problems Section 8.1 – Properties of Gases Goal: Describe the kinetic molecular theory of gases and the units of measurement used for gases. Summary: • In a gas, particles are so far apart and moving so fast that their attractions are negligible. • A gas is described by the physical properties: pressure (P), volume (V), temperature (T) in Kelvins (K)
