Energy Unit Review
1. A material that does not conduct heat well is called a(n)
Insulator
2. The total potential and kinetic energy of the particles in an object is called
Thermal energy
3. When generators are spun by turbines, they
Produce electricity
4. Heat, like work, is an energy transfer measured in
Joules
5. Heat is transferred from one particle of matter to another without the movement of matter itself in a process called
Conduction
The total energy of all the particles in a substance is called
Thermal energy
7. Kinetic energy increases as
Both mass and velocity increase
8. Examples of kinetic energy
Something that moves • A ball rolling down the street
9. The energy associated with motion is called
Kinetic energy
10. The rate at which energy is transferred is called
Power
11. The movement of thermal energy from a warmer object to a cooler object is called
heat
12. A change from one form of energy into another
Energy transformation
13. When you rub your hands together on a cold day, you use friction to convert
Mechanical thermal energy
14. The transfer of energy by electromagnetic waves is called
Electromagnetic energy
15. Something that stores chemical energy is
Food you eat a match a battery
16. Unlike kinetic energy, potential energy is
Stored energy
17. Energy is measured in units called
Joules
18. Any temperature on the Kelvin scale can be changed to Celsius by
Subtracting 273
19. A measure of the average kinetic energy of the individual particles in an object is called
Temperature
20. The law of conservation of energy states that when one form of energy is converted into another
Energy is not created or destroyed
21. A pole-vaulter first converts kinetic energy into
Elastic potential energy
22. Visible light is an example of
Electromagnetic energy
23. How would you calculate an object’s mechanical energy?
ME = KE+PE
24. Absolute zero is shown as 0 on which scale?
The Kelvin scale
25. Water freezes at 32 degrees on which temperature scale?
Fahrenheit
26. Moving water can be used to produce electricity because
Most energy can be transformed into other forms of energy
27. The ability to do work is called
energy
28. Energy stored in the nucleus of an atom is called
Nuclear energy
29. When fossil fuels are burned, their chemical potential energy is converted into
Thermal energy
30. What is the freezing point of water in degrees Celsius? What is the boiling point of water in degrees Celsius?
Freezing point = 0 degrees Boiling point = 100 degrees
31. Heated air moves from baseboard heaters to the rest of a room in a process called
Convection
32. The type of energy stored by fossil fuels such as coal is
Chemical potential energy
33. Potential energy that depends on height is called
Gravitational potential energy
34. No more energy can be removed from matter at
0 Kelvin
35. What type of conversion is taking place when natural gas is used to heat water?
Chemical Thermal
36. Niagara Falls is a good example of
PE KE
37. The energy associated with the motion and position of an object is
Mechanical energy
38. What type of energy does a spinning turbine have?
Mechanical
39. Heat transfer occurs from
warm objects to colder ones
