  1. 1. Changes in Matter
  2. 2. Physical Change
  3. 3. Physical Change• Physical Change: Any change that alters the form or appearance of matter
  4. 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. 5. 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• STATES OF MATTER • Solid • Liquid • Gas
  6. 6. 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• STATES OF MATTER • Solid • Liquid • Gas• Methods of separating mixtures • Filtration and distillation
  7. 7. Chemical Change
  8. 8. Chemical Change• Change in mater that produces one or more new substances
  9. 9. Chemical Change• Change in mater that produces one or more new substances• Produces new substances with properties different from those of original substance
  10. 10. Conservation of Mass
  11. 11. Conservation of Mass• Law of Conservation of Mass • Matter is neither created or destroyed
  12. 12. Matter and Thermal Energy
  13. 13. Matter and Thermal Energy• Energy is the ability to do work
  14. 14. Matter and Thermal Energy• Energy is the ability to do work• Chemical and Physical change includes a change in Energy
  15. 15. Matter and Thermal Energy• Energy is the ability to do work• Chemical and Physical change includes a change in Energy• Temperature is the measure of average energy of random motion particles of matter
  16. 16. Matter and Thermal Energy• Energy is the ability to do work• Chemical and Physical change includes a change in Energy• Temperature is the measure of average energy of random motion particles of matter• Thermal Energy: Total energy of all particles in an object
  17. 17. Matter and Thermal Energy• Energy is the ability to do work• Chemical and Physical change includes a change in Energy• Temperature is the measure of average energy of random motion particles of matter• Thermal Energy: Total energy of all particles in an object• Endothermic Change: Change in which energy is taken in
  18. 18. Matter and Thermal Energy• Energy is the ability to do work• Chemical and Physical change includes a change in Energy• Temperature is the measure of average energy of random motion particles of matter• Thermal Energy: Total energy of all particles in an object• Endothermic Change: Change in which energy is taken in• Exothermic Change: When energy is given off
