Jimmy held the end of a metal bar over a fire while holding on to the opposite end. After a few minutes, the end he was holding began to get very hot. Which of the following processes correctly describes the heat traveling from one end of the bar to the other?

• inducation

• radiation

• convection

• conduction

The light from the Sun heats a metal surface. This is an example of

• inducation

• radiation

• convection

• conduction

Heat can be transferred through conduction, convection, and radiation. What is necessary in order for heat to be transferred by conduction?

• Heat must be transferred through space.

• Heat must be transferred in the form of currents.

• The objects must be in direct contact with one another.

• The substances must be liquids or gases.

A slice of cheese is 3.0°C and is sitting on a dish that is 3.0°C. If the dish and cheese are in a refrigerator that is set to 3.0°C, which of the following statements is true?

• Heat will flow from the air in the refrigerator to the cheese and the dish.

• Heat will not flow because there is no temperature difference between the substances.

• The temperature of the air in the refrigerator will decrease and the temperature of the cheese will increase.

• The temperature of the cheese will increase and the temperature of the dish will decrease.
