1. List and define the types of kinetic energy.
(there are 5 terms + kinetic energy)
Electrical Energy-Energy used by the
movement of electrons (electricity)
Radiant Energy-Energy that comes from
waves in the EM spectrum (light)
Thermal Energy-Energy that deals with the
movement of molecules with an object
Sound energy-This is energy created from
vibrating particles
Mechanical energy-this energy often deals
with objects that are moving

2. List and define the type of potential energy.
(there are 4 terms + potential energy)
Chemical energy-Energy that is stored in the
bonds of atoms or molecules (get this from
food)
Elastic energy-This is energy that stores up
when an object changes shape from its
original shape and wants to “bounce back”
(rubber band etc.)
Gravitational energy-the type of energy that
has to do with an object’s position. (often
involves objects that are high up such as
roller coaster at the top of a hill)
Nuclear Energy-Energy that holds together
the nucleus of an atom Stars like the sun are
constantly releasing nuclear energy through
fusion and fission.

3. List 5 examples of energy flow charts.
When a roller coaster starts at top of hill and
goes down-gravitational-mechanical
Heating food on a microwave-electrical
(outlet) to mechanical (rotating plate)
Eating lunch and then running a milechemical (food) to mechanical (run)
Shooting a bow and arrow-elastic when
held back; mechanical once released
Radio playing music-electrical to sound

4. Complete and turn in your argument for the
claim; When the kinetic energy of an object
changes, energy is transferred to or from the
object.

5. What instrument and units are used to
measure temperature?
Thermometer-Celsius, Farenheit, Kelvin

6. When you are measuring the temperature
of an object what are you actually
measuring?
Average Kinetic energy of the molecules

7. What is the difference between heat and
temperature?
Heat measures the total kinetic energy of an
object, temperature measures the average
kinetic energy of an object

8. List and define each phase change. Be
sure to indicate if thermal energy is being
added or removed.
Melting-Thermal energy is added and a
solid becomes a liquid
Evaporation-When thermal energy is added
to a liquid causing it to become a gas
Freezing-When thermal energy is removed
turning a liquid into a solid
Condensation-When thermal energy is
removed turning a gas to a liquid
Deposition-When thermal energy is rapidly
removed from a gas instantly becoming a
solid
Sublimation-When thermal energy is rapidly
added to a solid to form a gas

9. Create a model to show changes due to
adding or removing thermal energy. Include
arrows and some of following vocabulary:
condensation, deposition, evaporation,
deposition, freezing, gas, liquid, solid,
melting, and sublimation. Remember
models include title, pics with labels,
separate explanation with vocab.
Show the model from your study guide

10. List the components or steps needed in an
investigation.
Objective, prediction, hypothesis,
independent and dependent variables,
constants, materials, procedures, analysis

11. What is the difference between an
independent and dependent variable?
Independent is what is changed or
manipulated in investigation; dependent is
what changes as a result of investigation or
the observed variable

13. A can of lemonade and a can of soda are
put in the sun for 2 hours. They both came
out of the fridge and had the same starting
temperature, but are not at the same
temperature after 2 hours. Explain why this
occurred. The thermal energy from the
lemonade will be removed from the air
around the blass and condensation will form
on the outside of the glass

14. How does the type of matter affect energy
transfer?
Different types of matter conduct heat
differently the keeping coffee hot lab should
have shown us this.

15. How does the mass of a substance affect
energy transfer?
Different masses transfer energy at different
rates. In the lab where we had different
amounts of water the 400 ml beaker should
have had less energy transfer losing less
temperature. The smaller amounts have
more energy transfer and drop the
temperature faster.

16. How does temperature affect energy
transfer?
When energy is transferred to an object the
molecules increase in speed and the
temperature rises
When energy is transferred from an object
the molecules decrease in speed and the
temperature drops

17. What is the difference in an insulator and a
conductor-relate this to how fast they
transfer thermal energy?
Conductors transfer thermal energy at a
faster rate than insulators do. For example, if
an object is hot like coffee an insulator
would keep the cup hottest the longest.

18. What is conduction? What is a real life
example of conduction?
Heat transfer through direct contact-Extouching a hot spoon on the stove

19. What is convection? What is a real life
example of convection?
During convection warm air rises and cooler
air sinks. Hot air balloons work through
convection.

20. What is radiation? What is a real life
example of radiation?
Energy transfer via electromagnetic waves.
