Chapter 15 Kinetic Molecular Theory
Kinetic Theory • All matter is composed of tiny particles.
Kinetic Theory • All matter is composed of tiny particles • Atoms
Kinetic Theory • All matter is composed of tiny particles • Atoms • Molecules
Kinetic Theory • All matter is composed of tiny particles • Atoms • Molecules • Ions
Kinetic Theory • These tiny particles are in constant motion. Liquid Gas Solid
Kinetic Theory • Collisions between moving particles are perfectly elastic. • In an elastic collision there is no net change in kinetic energy.
Pressure depends on two factors Force Area Pressure = Pressure Force Area
Temperature • How hot or cold • Average kinetic energy
How do we lower temperature? • We slow down the particles.
Absolute Zero K = °C + 273 °C = K - 273
Kinetic Energy KE = ½ mv2 When considering kinetic energy we must consider two factors. • Mass • Velocity
