Matter

2. Physical Change

3. Physical Change
• Physical Change: Any change that alters the form
or appearance of matter

4. Physical Change
• Physical Change: Any change that alters the form
or appearance of matter
• A substance that undergoes a physical change is
still the same substance after the change

5. Physical Change

still the same substance after the change
• STATES OF MATTER
• Solid
• Liquid

7. Chemical Change

8. Chemical Change
• Change in mater that produces one or more new
substances

9. Chemical Change
• Change in mater that produces one or more new
substances
• Produces new substances with properties
different from those of original substance
