c. Radiation
d. Insulation
3. Mrs. Klem is boiling a pot of
water to make macaroni and
cheese. As she boils the water,
she notices that it moves in a
circular motion. Which of the
following describes how the
water is being heated?
a. Conduction
b. Convection
c. Radiation
d. Evaporation
4. The picture shows bottled water and
tap water in a glass. The bottled water
is added to the tap water. How does
the heat transfer?
a. The heat transfers
from the bottled
water to the tap water by radiation.
b. The heat transfers from the bottled
water to the tap water by
conduction.
c. The heat transfers from the bottled
water to the tap water by
convection.
d. Heat is not transferred.
5. Which of the following is an
example of conduction?
a. The air in a heated room
moves in circular patterns
b. A bright lamp makes a
person sweat
c. A spoon sitting on a stove
heats up
d. Magma moves in circles in
the mantle
6. The air directly above the fire is
heated and warms the hands
above the fire. How do the
hands get heated at point A?
a. Radiation
b. Convection
c. Conduction
d. Condensation
7. A man holds a metal poker
above the fire. How is heat
being transferred from the rod to
the man’s hand?
a. Radiation

heat transfer occurs when cool
water absorbs the heat while in
contact with the hot engine?
a. Radiation
b. Convection
c. Condensation
d. Conduction
10. Below is a picture of a how the sun
