6/6/11 Chapter 5 Gases and the Kinetic-molecular Theory 22 Three Phases of Matter: Gas Liquid Solid Particles are far apart The particles of a gas fill up the space in which they are contained. Compressible Particles are close together Not compressible Particles are tightly packed Not compressible

6/6/11 Chapter 5 Gases and the Kinetic-molecular Theory 33 Gas Liquid Solid Particles are very mobile. -High velocities -In constant motion Particles move with less freedom of motion Particles are not mobile Negligible attractive forces between gas particles Take the shape and volume of the container Moderate attractive forces Liquids take the shape but not the volume of the container Strong attractive forces. Do not take the shape or volume of container.

55 Chapter 5 Gases and the Kinetic-molecular Theory Because the volume of an individual gas particle is so small compared to the volume of its container, the gas particles are considered to have negligible volume (zero volume). Gas particles are in constant, random, straight-line motion except when they collide with each other or with the container walls. The particles are assumed to exert no forces on each other. The average kinetic energy of a collection of gas particles is
