28. What is the cleanest burning fossil fuel?
natural gas
30. What unit is both energy and work expressed in.
Joules
4. WHAT TYPE OF ENERGY CONVERSION TAKES PLACE WHEN YOU RIDE YOUR BIKE?
CHEMICAL ENERGY FROM THE FOOD THE RIDER ATE IS BEING CONVERTED TO THERMAL ENERGY; THERMAL ENERGY IS CHANGED INTO MECHANICAL ENERGY AS THE RIDER PEDALS
25.WHAT WAS PETROLEUM FORMED FROM?
THE REMAINS OF ORGANISMS THAT WERE IN SHALLOW PREHISTORIC LAKES AND SEAS
5. WHAT ENERGY CONVERSIONS ARE TAKING PLACE WHEN YOU TURN ON YOUR BLOW DRYER?
ELECTRIC ENERGY CONVERTS TO SOUND AND THERMAL ENERGY
2. Describe sound energy
energy caused by an object's vibrations
6. WHAT TYPE OF ENERGY CONVERSION OCCURS WHEN YOU TURN ON A FLASHLIGHT?
CHEMICAL ENERGY (FROM THE BATTERY) IS CHANGED INTO LIGHT ENERGY AND SOME THERMAL ENERGY
29.WHAT WAS COAL FORMED FROM?
THE REMAINS OF PLANTS THAT WERE IN SWAMPS MILLIONS OF YEARS AGO
33. HOW IS ENERGY CONVERSION DIFFERENT FROM THE LAW OF CONSERVATION OF ENERGY? (Short Answer)
ENERGY CONVERSION IS WHEN ONE FORM OF ENERGY IS CHANGED INTO ANOTHER FORM OF ENERGY.
THE LAW OF CONSERVATION OF ENERGY SAYS THAT ENERGY CANNOT BE CREATED OR DESTROYED-ONLY TRANSFERRED.
36.WHAT IS AN ENERGY RESOURCE CALLED THAT CANNOT BE REPLACED AFTER THEY ARE USED OR CAN BE REPLACED ONLY AFTER THOUSANDS OR MILLIONS OR YEARS?
NONRENEWABLE RESOURCE
43. WHAT ENERGY CONVERSION OCCURS WHEN BATTERIES ARE USED?
CHEMICAL ENERGY CONVERTS TO ELECTRICAL ENERGY
9.IS PETROLEUM A RENEWABLE OR NONRENEWABLE RESOURCE?
NONRENEWABLE--IT IS A FOSSIL FUEL
49. Describe thermal energy
a measure of particle motion
27. DEFINE ENERGY.
THE ABILITY TO DO WORK
50. Describe light energy
the result of vibrations of electrically charged particles
47. IS WATER A RENEWABLE OR NONRENEWABLE RESOURCE?
RENEWABLE
3. WHAT ENERGY CONVERSIONS ARE TAKING PLACE WHEN YOUR WATER HEATER IS TURNED ON?
ELECTRICAL ENERGY CONVERTS TO THERMAL ENERGY
35. WHICH NONRENEWABLE RESOURCE IS USED THE MOST TO HEAT BUSINESSES AND HOMES?
NATURAL GAS
42. WHERE DID FOSSILS FUELS ORIGINALLY RECEIVE THEIR ENERGY FROM?
THE SUN
1. WHAT TYPE OF ENERGY CONVERSION OCCURS WHEN YOU COOK IN THE MICROWAVE?
ELECTRICAL ENERGY IS CHANGED INTO LIGHT ENERGY AND THEN INTO THERMAL ENERGY WHEN THE FOOD IS HEATED.
20. IS NATURAL GAS A RENEWABLE OR NONRENEWABLE RESOURCE?
NONRENEWABLE. IT IS A FOSSIL FUEL.
10. IS THE SUN A RENEWABLE OR NONRENEWABLE RESOURCE?
RENEWABLE
38. WHAT IS ELECTRICAL ENERGY CALLED THAT IS PRODUCED FROM FALLING WATER?
HYDROELECTRICITY
23. WHAT IS ORGANIC MATTER THAT CAN BURNED TO RELEASE ENERGY CALLED?
BIOMASS
11. GIVE 3 EXAMPLES OF BIOMASS.
PLANTS, WOOD, WASTE
44. IF THE SUN'S NUCLEAR ENERGY WERE EXHAUSTED, WHAT WOULD HAPPEN TO OUR ENERGY RESOURCES ON EARTH?
WE WOULD RUN OUT OF ENERGY RESOURCES AND EVERYTHING ON EARTH WOULD DIE.
14. Describe electrical energy
the energy of moving electrons
24. What energy conversion occurs during photosynthesis
plants use light energy to produce new substances with chemical energy
34. DESCRIBE FOSSIL FUELS AND BIOMASS FROM THEIR SOURCE TO THEIR USE. (Short Answer)
FOSSIL FUELS FORMED FROM PLANT AND ANIMAL REMAINS MILLION OF YEARS AGO. BIOMASS FORMED FROM LIVING THINGS TODAY. BOTH CAN BE BURNED TO RELEASE CHEMICAL ENERGY WHICH CAN THEN BE CONVERTED TO OTHER ENERGY
46. NAME THE FIVE TYPES OF ENERGY THAT ARE CONSIDERED RENEWABLE RESOURCES.
SOLAR ENERGY
ENERGY FROM WATER
WIND ENERGY
GEOTHERMAL ENERGY
BIOMASS
41. WHAT DO FOSSIL-FUEL AND NUCLEAR POWER PLANTS USE TO TURN A TURBINE THAT ROTATES THE GENERATOR?
STEAM
32.If fossil fuels are nonrenewable, why do we use them for energy?
They provide alot of thermal energy per unit of mass.
8. WHAT TYPE OF ENERGY CONVERSION OCCURS WHEN YOU MAKE A CAKE?
CHEMICAL ENERGY (FROM THE CAKE INGREDIENTS-WHICH ARE CHEMICALS) IS CHANGED INTO THERMAL ENERGY WHEN IT IS COOKED IN THE OVEN.
17. Give 3 examples of fossil fuels
gasoline,coal, natural gas
18. What is our most important energy resource?
the sun
31. WHERE IS MOST COAL IN THE U.S. BURNED TODAY?
POWER PLANTS TO RUN ELECTRIC GENERATORS
40. WHAT IS AN ENERGY RESOURCE CALLED THAT CAN BE USED AND REPLACED IN NATURE OVER A RELATIVELY SHORT PERIOD OF TIME?
RENEWABLE RESOURCE
7. WHAT TYPE OF ENERGY CONVERSION OCCURS WHEN YOU TURN ON A LIGHT?
ELECTRICAL ENERGY IS CHANGED INTO LIGHT ENERGY (AND THERMAL ENERGY)
22. True or False An object that has kinetic energy must be in motion.
true
48. IS COAL A RENEWABLE OR NONRENEWABLE RESOURCE?
NONRENEWABLE
13. WHAT ENERGY CONVERSIONS ARE TAKING PLACE WHEN YOU TURN ON THE TOASTER?
ELECTRICAL ENERGY CONVERTS TO THERMAL ENERGY AND LIGHT ENERGY
26. True or False When one object does work on another, energy can be created or destroyed.
False. Energy can only be transferred, not created or destroyed.
39. WHAT ENERGY CONVERSION TAKES PLACE WHEN A PERSON EATS FOOD?
CHEMICAL ENERGY CHANGES INTO THERMAL ENERGY
37. WHAT ARE ENERGY RESOURCES THAT FORMED FROM THE BURIED REMAINS OF PLANTS AND ANIMALS THAT LIVED MILLIONS OF YEARS AGO CALLED?
