5.P.3.1 Conduction, Convection, and Radiation

Which is the best example of heat transfer through radiation?

• heating soup in a pot on the stove

• standing by a campfire to get warm on a chilly night

• burning your hand when touching a hot pan on the stove

• not getting burned when touching a wooden spoon that has been in a hot pan

Which is the best example of conduction?

• boiling a pot of water

• feeling heat from a fireplace

• a hot air balloon rising and falling

• touching a hot handle and getting burned

When Julie was cooking macaroni she noticed that it would rise to the top of the boiling water and then sink back to the bottom of the pot. This is most likely because

• The convection of heat within the water was creating a current.

• The convection of air around the pot was creating a current.

• The conduction of heat within the water was creating a current.

• The conduction of air around the pot was creating a current.

Why does an ice cube melt when dropped into hot liquid?

• The liquid absorbs heat from the ice.

• Heat from the liquid transfers to the ice.

• Heat from the ice transfers to the liquid.

• Cold from the ice transfers into the liquid.

What best explains why hot air rises above a dark parking lot?

• The dark parking lot heats up the air. The hot air rises by conduction.

• The dark parking lot heats up the air. The hot air rises by convection.

• The dark parking lot heats up the air. The hot air rises by insulation.

• The dark parking lot heats up the air. The hot air rises by radiation.

How does heat energy from the Sun reach Earth?

• radiation

• solar wind

• conduction

• convection

Jake is wearing gloves while he gets a hot pan out of the oven. Which best explains why Jake needs to wear gloves while he is carrying the hot pan?

• The gloves protect his hands from convection heat in the hot pan.

• The gloves protect his hands from heat that is radiated through the hot pan.

• The gloves protect his hands from heat that is conducted through the hot pan.

• The gloves protect his hands from heat that enters the pan from the surrounding air.
