Changes in Matter
Physical Change
Physical Change• Physical Change: Any change that alters the form
or appearance of matter
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

• A substance that undergoes a physical change is still the same substance after the change
• STATES OF MATTER
• Solid
• Liquid
• Gas
• Methods of separating mixtures
• Filtration and distillation
Chemical Change
Chemical Change
• Change in mater that produces one or more new substances
Chemical Change
• Change in mater that produces one or more new substances
• Produces new substances with properties different from those of original substance
Conservation of Mass
Conservation of Mass
• Law of Conservation of Mass
• Matter is neither created or destroyed
