Heat transfer

When placed in direct sunlight, which object will absorb the most radiated heat energy?

• A black sweater

• Aluminum foil

• A snowball

• A white sweater

Which of the following best describes the energy that a hamburger has in terms of its usefulness to provide energy of a human being?

• Atomic

• Elastic

• Kinetic

• Potential

Jose placed his water in the freezer overnight. Before ha takes it to school, he wraps the water bottle in a wool sock to keep the water cold throughout the day. Which of the following best justifies Jose's action?

• The wool prevents the water bottle from losing thermal energy

• The wool holds in the condensation which keeps the water cool

• The wool reflects light that might warm the water bottle

• The wool prevents heat from the warmer outside air to the water

Which of the following best describe what happens when ice is placed in a warm glass of water?

• Heat from the glass moves through the liquid to melt the ice through radiation

• The ice transfers the cold temperatures to the surrounding water through convection

• The ice floats to the top but small pieces brake off and are suspended in the liquid to cool through heat convection

• The heat from the surrounding liquid is transferred to the ice through conduction

Fill in the blank. Thermal energy is transferred through conduction from a substance at a __________ to a substance at a __________.

The form of heat transfer that occurs between the sun and the outer lay of the skin is called what?

• Conduction

• Radiation

• Convection

• Evaporation

When descending the stairway in a house on a cold, cloudy day, you notice that as you go downstairs the air is warmer near the ceiling than at the floor of the first floor rooms. this is most likely an example of the result of which form of heat transfer?

• Conduction

• Convection

• Radiation

• Transmission

Based on your understanding of heat transfer, infer which material would work best to prevent heat transfer to a surface if it were placed on the surface to block the sun?

• Silver Mylar

• Red wool blanket

• Clear bubble rap

• White construction paper

Which of the following modes of heat transfer is illustrated when cold water sinks to the bottom of a lake because it is denser and pushes the warmer water up and out of the way?

• Conduction

• Convection

• Radiation

• Transmission

answer the following question.

• There was more light shining on the spoon on the left allowing more radiant heat

  transfer to the ice cube on the metal spoon causing the ice cube on the left to melt

  faster.

• The person holding the metal spoon on the left has a higher body temperature than

  the person holding the spoon on the right causing the ice cube on the left to melt faster

• The structure of the atoms in the metal spoon allow for a slower transfer of heat

  from the spoon to the ice compared to the rate of heat transfer from the plastic spoon

  to the ice cube.

• The structure of the atoms in the metal spoon allow for a more rapid transfer of

  heat from the spoon to the ice cube compared to the rate of heat transfer from the

  plastic spoon to the ice cube
