Introduction:
Heat always travels from a ______ object to a ______ object.
1. Conduction
a. What substances make good
conductors?
b. What substances make bad
conductors (good insulators)?
c. What is conduction?
d. The better the conductor the more _______ heat will transfer.
e. In conduction, do the substances need to be touching each other? Explain.
2. Convection
a.
Draw a picture of a convection current.
Label the red and blue arrows.
b. What is convection?
c.
What are some other examples of convection?
d. Convection is the primary method that heat
transfers in _______ and _____.
e. Which is denser, cold air or warm air? Explain.
3. Radiation
a. What effect does the sun's
radiation have on the temperature of the house?
b. What are some other examples
of radiation heat transfer?
c. Radiation can travel
through empty space. True or False?
1. Can you “beat the heat”? How far
can you go? Your goal is to make it to Level 10; when you do, show me that you've completed your task.

Now, take the online quiz on
Thermodynamics; write the answers in your notebook.
- 1. Compare/Contrast the molecules of
solids at different temperatures and the molecules of liquids at different
temperatures.
- 2. The Kinetic theory of matter states: All matter is made up of ______
and ________ that are constantly ______.
1. In conduction, thermal energy moves
from ____ to ____.
2. Look at Table 2.2 “Heat Conductivity
of Various Substances”
a. List in order of high conductivity
(conductor) to low conductivity (insulator): wood, water, silver, air, and
iron.
b. Rank the three states of matter in their ability to conduct heat.
b. Rank the three states of matter in their ability to conduct heat.
3. Give a brief description of
atmospheric convection.
4. What are four examples of
radiation? (The website gives you two; think of two new examples.)
5. Draw a picture of conduction,
convection, and radiation. Label them correctly.
1. Read Convection, Conduction, and
Radiation
2. Play the Heat Review game at the
bottom of the page
1. What happens to the volume of objects when they absorb thermal energy?
2. What happens to the volume of objects when they release thermal energy?
I. In the transfer of
thermal energy, or movement of heat, how does radiation differ from conduction
and convection?
J. Write down
observations, thoughts, inferences on each method of heat transfer: conduction,
convection, radiation.
