Thermal Energy Transfer Review

Burning your hand on a hot pan is an example of

• conduction.

• convection.

• radiation.

The transfer of heat energy through direct contact is

• conduction.

• convection.

• radiation.

What heat transfers by the rising of warm molecules and falling of cool molecules?

• Conduction

• Convection

• Radiation

Heat transfer always occurs

• from cold to hot.

• from hot to cold.

• in any direction.

The turtle stays warm because the lamp _____________

• Turns electrical energy into thermal enrgy.

• Conserves energy by ionizing molecules around it.

• Causes kinetic energy to turn to potential energy.

• Decreases the molecular motion of the molecules around it.

A student used a thermometer to measure the temperature at three places and recorded the data in a table. Which statements represent the conclusions you can support with the data? Select all that apply

• The temperature of the sidewalk is the same as the street

• Energy has been transferred from the street to the air above the street

• Energy has been transferred from the lawn to the street and sidewalk through conduction

• The street surface has absorbed more radiant thermal energy than the sidewalk
