KINETIC MOLECULAR THEORY - STEPHEN JAY RUGA.pptx

It discusses the aspect of kinetic Molecular theory, it's function, purposes and formation

1. Kinetic Molecular Theory Reporter: Stephen Jay Ruga

2. OBJECTIVES 02 Explain the different properties of gases, liquid, and solid in terms of kinetic molecular theory 01 Define what is Kinetic Molecular Theory; and

3. What is Kinetic Molecular Theory?

4. Kinetic Molecular Theory It explains the properties of solids, liquids and gases in terms of intermolecular forces of attraction and the kinetic energy of the individual particles.

5. Definition of concepts These are forces that act between molecules holding them together causing them to interact. Intermolecular Forces of Attraction This is the energy of motion; the higher the kinetic energy, the faster the particles move. Kinetic Energy

6. 1. All matter is made up of tiny particles. 2. These are particles are in constant motion. 3. The speed of particle is proportional to temperature. Increased temperature means greater speed. Solids, liquids, and gases differ in distances between particles, in the freedom of motion of particles, and in the extent to which the particles interact. Kinetic Molecular Theory
