1. CH 2 SEC 3 ENERGY AND MATTER

2.  ENERGY- IS THE ABILITY TO DO WORK OR CAUSE CHANGE.  KEY- EVERY CHEMICAL OR PHYSICAL CHANGE IN MATTER INCLUDES A CHANGE IN ENERGY.  KEY- LIKE MATTER ENERGY IS NEITHER CREATED OR DESTROYED IN CHEMICAL REACTIONS, BUT CAN CHANGE FROM ONE FORM TO ANOTHER! ENERGY

4.  EXAMPLE- WHEN CHARCOAL BURNS IT RELEASES ENERGY IN THE FORM OF HEAT AND LIGHT.  KEY- FORMS OF ENERGY RELATED TO CHANGES IN MATTER INCLUDE; THERMAL ENERGY, CHEMICAL ENERGY, ELECTROMAGNETIC ENERGY, AND ELECTRICAL ENERGY. ENERGY AND MATTER

5. FORMS OF ENERGY

6.  TEMPERATURE- IS A MEASURE OF THE AVERAGE ENERGY OF RANDOM MOTION OF PARTICLES OF MATTER  THERMAL ENERGY- IS THE TOTAL ENERGY OF ALL THE PARTICLES IN AN OBJECT. EX- HOT CUP OF COFFEE RELEASING T. E.  THERMAL ENERGY- ALWAYS FLOWS FROM WARMER MATTER TO COOLER MATTER TEMP AND THERMAL ENERGY

7. EARTHS TEMPERATURE

9. COPY TO NOTES

10.  ENDOTHERMIC CHANGE- IS CHANGE WHEN ENERGY IS TAKEN IN.  EX- ICE MELTING, THE ICE TAKES IN THE ENERGY FROM IT SURROUNDINGS FORMS OF ENERGY

11. TIP OF THE ICEBERG ENDOTHERMIC

12.  EXOTHERMIC CHANGE- ENERGY IS GIVEN OFF.  EX-WHEN CHARCOAL BURNS IT RELEASES ENERGY IN THE FORM OF LIGHT AND HEAT CHANGES IN ENERGY

13. EXOTHERMIC

14.  KEY- DURING A CHEMICAL CHANGE, CHEMICAL ENERGY MAY BE CHANGED TO OTHER FORMS OF ENERGY.  EX- WHEN YOU PUSH A BIKE AND YOURSELF UP A HILL, CHEMICAL ENERGY FROM FOODS YOU ATE IS TRANSFORMED INTO ENERGY OF MOTION. TRANSFORMING ENERGY

15.  KEY- ONE OF THE MOST IMPORTANT ENERGY TRANSFORMATIONS ON EARTH THAT INVOLVES CHEMICAL ENERGY IS PHOTOSYNTHESIS.  KEY- DURING PHOTOSYNTHESIS, PLANTS TRANSFORM ELECTROMAGNETIC ENERGY FROM THE SUN INTO CHEMICAL ENERGY AS THEY MAKE MOLECULES OF SUGAR.  KEY- WHEN WE EAT PLANTS AND ANIMALS WE TRANSFORM THE ENERGY ONCE AGAIN TO ENABLES US TO LIVE.
