Michelle wants to roast marshmallows over a fire. Which best explains how this process happens?

• The warmth of the fire is conducted into the marshmallow.

• The warmth of the fire is radiated into the marshmallow.

• The coolness of the marshmallow is conducted into the fire.

• The coolness of the marshmallow is radiated into the fire.

Which substance will conduct the least amount of heat?

• glass

• copper

• plastic

• aluminum

A student places a cup of cold water on a counter in a hot room. After a short time, the

student notices that the water in the cup is no longer cold. Which best explains why the

water in the cup is no longer cold?

• The coldness of the water transferred to the air, making the water in the cup warmer.

• The coldness of the water was conducted to the cup, making the water in the cup

  warmer.

• The heat from the air transferred to the water in the cup, making the water in the cup

  warmer.

• The heat from the air caused the cold water in the cup to condense, making the water

  warmer.

Sandra washed her hair. She dried it with warm air from a blow dryer before going to school. Which statement best explains why the blow dryer was able to dry Sandra’s hair quickly?

• The blow dryer used electricity.

• The blow dryer transferred heat.

• The blow dryer created sound waves.

• The blow dryer used mechanical energy.

Which best explains how bacon is fried on a stove burner?

• The bacon creates a convection current, the heat rises to the pan, and

  then rises to the stove burner.

• The bacon transfers heat directly to the pan, and the pan transfers

  heat directly to the stove burner.

• The stove burner radiates heat to the pan, and the pan radiates heat

  to the bacon.

• The stove burner transfers heat directly to the pan, and the pan

  directly transfers heat to the bacon.

Which is the best example of heat transfer by convection?

• frying bacon in a pan

• sea breeze at the beach

• melting ice in your hand

• burning your finger on the stove

Mrs. Warren’s class is learning about heat transfer. Her class observes a pot of boiling water and describes the process. The students note that as the water at the bottom heats up, it rises. The cool water at the top falls, and the cycle continues. Which best describes the process the students are observing?

• conduction

• convection

• radiation

• transformation

How does heat energy from the Sun reach Earth?

• radiation

• solar wind

• conduction

• convection

Joe is cooking dinner on the stove. When he picks up the pan by the handle, he burns his hand. Which form of heat transfer caused Joe to burn his hand?

• radiation

• conduction

• convection

What conditions are necessary for heat conduction to occur between two objects?

• The objects must be surrounded by air or water.

• Two objects at different temperatures are touching one another.

• Two objects at different temperatures are located close to one another.

• One object must emit energy as light and heat and another object absorbs the energy.
