STATES OF MATTER 0620 IGCSE Chemistry Summer Plan Teacher Andrea Montalván LESSON OBJECTIVES At the end of the lesson, you should be able to: State the distinguishing properties of solids, liquids, and gases. Describe the structure of solids, liquids, and gases in terms of particle separation, arrangement, and types of motion. SOLID has definite shape and volume has particles that are packed closely together and usually arranged in a regular pattern LIQUID has definite volume, but has no fixed shape has particles that can move and are in close contact GAS has no definite volume and shape has particles that are widely separated LET´S BEGIN LOOK AT THIS DIAGRAM PLASMA has no definite volume and shape has charged particles that are widely separated EXAMPLES OF PLASMA lightning fireball flame comet's tail SUMMARY Solid Liquid Gas Plasma has particles that are packed closely together has particles that can move and are in close contact has particles that are widely separated has charged particles that are widely separated KINETIC THEORY KINETIC THEORY KNOW THE DIFFERENCE It all about the mixing Elements Mixtures Compounds
