2. Definitions Kinetic refers to motion Kinetic Theory: All matter consists of tiny particles that are in constant motion. These particles are usually molecules or atoms.

3. Fundamental Assumptions About Gases from the Kinetic Theory The particles in a gas are considered to be small, hard spheres with an insignificant volume. The motion of each particle is independent of all other particles. The motion of the particles in a gas is rapid, constant, and random. Particles only change directions when colliding with other particles or other objects. All collisions between particles in a gas are perfectly elastic. During an elastic collision, kinetic energy is transferred without loss from one particle to another so total kinetic energy remains constant.

4. Objectives #1 and #2 1. Explain why term “kinetic” makes sense when speaking about particle behavior. “Kinetic” means relating to motion, and the kinetic theory is when the tiny particles of matter are in constant motion. 2. How does a gas behave according to the kinetic molecular theory (KMT)? (What are the three basic principals?) The particles in a gas are considered to be small, hard spheres with an 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. Objectives #3 and #4 3. Why is the motion of one particle independent of another particle in a gas sample? They’re far apart from each other with empty space between them. No attractive/repulsive forces exist between the particles. 4. Define elastic collision. Elastic collision is when kinetic energy is transferred without loss from one particle to another, and the total kinetic energy remains constant.
