properties of matter.ppt
- 2. MATTER IS EVERYWHERE AND EVERYTHING! MATTER IS ANTHING THAT TAKES UP SPACE! MATTER IS MADE UP OF TINY PARTICLES CALLED ATOMS!
- 3. •Anything that has a mass and a volume
- 4. Matter can be found in three different types. These three types are considered the three STATES of MATTER. 1. Solids 2. Liquids 3. Gasses
- 5. A SOLID is matter that has a defined shape and will not lose its shape. FIXED VOLUME AND FIXED SHAPE Examples of solids: 1. Chair 2. Table 3. Golf Ball 4. Hockey Puck 5. Glass Jar
- 6. A LIQUID is matter that will take the shape of any container it is placed in put has a fixed volume. Examples of LIQUIDS: 1. Water 2. Soda 3. Milk 4. Juice 5. Tomato Sauce
- 7. A GAS is matter that does NOT have a fixed shape or volume, but will completely take up all the space in a container. MOST GASSES ARE INVISIBLE!!!! Examples of GASSES: 1. Oxygen 2. Helium 3. Carbon Dioxide 4. Nitrogen 5. Carbon Monoxide
- 8. Although matter can be classified into three different states (types) it can also be described using its properties. PROPERTIES: Characteristics, features, qualities, or traits.
- 10. Matter can go through two different types of changes. Types of Changes: 1. Physical 2. Chemical
- 11. A physical change in matter is when matter changes its property but not it’s chemical nature.
- 12. Physical changes: Although some properties (like shape, phase, etc.) of the material change, the material itself is the same before and after the change. The change can be “undone.”
- 13. Examples: Changes in 1. Shape 2. Texture 3. Size 4. Dissolves 5. Breaks Apart
- 14. EXAMPLES: Aluminum foil is cut in half Clay is molded into a new shape Butter melts on warm toast Water evaporates from the surface of the ocean Juice freezes Rubbing alcohol evaporates on your hand
- 15. A chemical change in matter is when matter becomes something completely new. New matter is formed.
- 16. Chemical change: The substances present at the beginning of the change are not present at the end; new substances are formed. The change cannot be “undone."
- 17. CHEMICAL CHANGES THE MATTER IS DIFFERENT. THE PARTICALES OF THE SUBSTANCES ARE BROKEN APART THE OLD MATTER IS NO LONGER PRESNT ATOMS ARE REARRANGED INTO NEW PARTICLES THE ORIGINAL MATTER CANNOT BE REMOVED FROM THE NEW MATTER A NEW SUBSTANCE IS FORMED
- 18. EXAMPLES: Milk goes sour Jewelry becomes tarnished Bread becomes toast Rust forms on a nail Gasoline is ignited Hydrogen peroxide bubbles in a cut A match is lit Your body digests food Fruit decomposes and rots
- 19. HOMEWORK
- 20. Every object can be described based on it’s weight. The heavier an object is the more it weigh’s.
