CH 2 SEC 3 ENERGY AND MATTER
GOAL/PURPOSE STUDENTS WILL LEARN ABOUT THE DIFFERENT FORMS OF ENERGY STUDENTS WILL LEARN THAT ENERGY CAN BE RELEASED OR ABSORBED
ENERGY 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 AND MATTER 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.
TEMP AND THERMAL ENERGY 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
FORMS OF ENERGY ENDOTHERMIC CHANGE- IS CHANGE WHEN ENERGY IS TAKEN IN. EX- ICE MELTING , THE ICE TAKES IN THE ENERGY FROM IT SURROUNDINGS
CHANGES IN ENERGY EXOTHERMIC CHANGE- ENERGY IS GIVEN OFF. EX-WHEN CHARCOAL BURNS IT RELEASES ENERGY IN THE FORM OF LIGHT AND HEAT
TRANSFORMING ENERGY 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.
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.
