1. Principles of Chemistry States of matter by A. Genus

2. At the end of this lesson students should be : Able to demonstrate an awareness that matter is made up of particles Aware of the different forces of attraction that exist between particles. General Objectives

3. Specific Objectives At the end of this lesson students should be able to accurately: Define the term ‘matter’ after discussion in class. state two evidence in support of the particulate nature of matter after discussion in class and practical work involving processes, such as diffusion and osmosis Explain at least five differences between the three states of matter in terms of energy and arrangement of particles(considering freezing, melting, boiling, sublimation and condensation) after discussion in class.

4. Matter Is Anything that has mass and occupies space And has three states Liquid Solid Gas

5. Comparison of the three states of matter

7. Interconversions between the states of matter

8. Interconversions between the three states of matter

9. Osmosisis the movement of particles from a hypotonic solution to a hypertonic solution through a selectively permeable membrane

10. Diffusionisthe movement of particles from a region of high concentration to a region of low concentration until the particles are evenly distributed.

11. Revision Questions What is matter? List the three states of matter? State the interconversions between the states of matter. Compare the three states of matter based on arrangement of their particles and interparticle forces. What is diffusion? Give one example. What is osmosis? Give one example.
