3. 3. What is not matter <ul><li>Sunlight </li></ul><ul><li>Shadows </li></ul><ul><li>Heat </li></ul><ul><li>Fire </li></ul><ul><li>Energy </li></ul><ul><li>Noise </li></ul><ul><li>Sounds </li></ul><ul><li>Electricity </li></ul>
4. 4. Matter can exist in 3 states : <ul><li>Solid </li></ul><ul><li>Liquid </li></ul><ul><li>Gas </li></ul>
5. 5. Properties of Solid <ul><li>Definite shape – does not take the shape of the container </li></ul><ul><li>Definite volume </li></ul><ul><li>It will not change no matter what container it is placed in. </li></ul>
6. 7. Properties of Liquid <ul><li>No definite shape –takes the shape of the container </li></ul><ul><li>Glue, dew, tears, blood, oil, petrol, milk, honey mercury are all liquids. As long as they can flow, they are liquids. </li></ul><ul><li>Definite volume </li></ul><ul><li>It will change and take the shape of the container it is placed in. </li></ul>
7. 9. Properties of Gas <ul><li>No definite shape –takes the shape of the container </li></ul><ul><li>Carbon dioxide, oxygen, hydrogen, steam, water vapour ,nitrogen are all gases. Not all gases are invisible. </li></ul><ul><li>No definite volume and can be compressed. </li></ul><ul><li>It will take the volume of the container it is placed in. </li></ul><ul><li>100 cm ³ of gas added to 200 cm³ container will have a final volume of 200 cm³ of gas. </li></ul>
8. 11. <ul><li>If the syringe is filled with oxygen, can the piston be pressed? </li></ul><ul><li>Yes, it can because oxygen is a gas and gases can be compressed. </li></ul><ul><li>If the syringe is filled with water, can the piston be pressed? </li></ul><ul><li>No, it cannot because water is a liquid and liquids cannot be compressed. </li></ul>
9. 12. Butter <ul><li>Butter can exist in 3 states : </li></ul><ul><li>Solid - when it is refrigerated </li></ul><ul><li>Liquid – when it is melted </li></ul><ul><li>Gas – when it is heated. </li></ul>
10. 13. Wax <ul><li>Wax can exist in 3 states </li></ul><ul><li>Solid – cooled wax </li></ul><ul><li>Liquid – hot dripping wax </li></ul><ul><li>Gas – burning at the wick. </li></ul>
11. 14. Sponge <ul><li>A sponge is a solid yet it changes its shape when it is pressed down. Why? </li></ul><ul><li>It has a lot of air trapped inside it (the holes) and it is the air that is compressed, causing the sponge to look smaller and change shape. </li></ul>
