Chapter 13: States of Matter

1. Chapter 13:States of Matter Particle Motion

2. Why does the term kinetic make sense when talking about Particle Motion? • “Kinetic” refers to motion. • “Kinetic Energy” is the energy an object has because of its motion. • “Kinetic Theory”:“All matter consists of tiny particles that are in constant motion”

3. THEREFORE…. • If particles are in constant motion and “Kinetic” refers to motion, the two correlate! • Q.E.D

4. How does a gas behave according to the “Kinetic Molecular Theory”? • The particles in a gas are considered to be small hard spheres with insignificant volume. • The motion of the particles in a gas is rapid, constant and random. • All collisions between particles in a gas are perfectly elastic.

5. Why is the motion of one particle independent of another particle in a gas sample? • The particles are relatively far apart. • Between these particles there is empty space. • Because there is empty space there are no attractive or repulsive forces existing between the particles.

6. Define Elastic Collision • In an elastic collision, kinetic energy is transferred without loss from one particle to another, so it remains constant. • Elastic collision occurs between gas particles.
