Thermal Energy Exchange Quiz

Which of the following best describes CONDUCTION?

• When heat is transferred through waves of heat across a distance.

• When heat is transferred through circulation of liquid or gases

• When heat transfers from objects that are touching.

• When the particles stop moving because they have reached absolute zero

__________ is the transfer of heat by the movement of a fluid.

• Kinetic Energy

• Conduction

• Radiation

• Convection

In the context of Thermal Energy, "fluid" refers to:

The Sun warms your skin on a cold day.

This is an example of...

• Conduction

• Convection

• Radiation

• Insulation

You burn your hand by touching a hot stove.

This is an example of...

• Conduction

• Convection

• Radiation

• Protons

Answer explanation

This is an example of heat transfer that is happening between 2 solid objects (the stove and the hand). Conduction happens when 2 objects come into contact and there is a thermal energy exchange (meaning that the stove heats up the hand because the hand is colder than the stove)

A hot air balloon rises.

This is an example of....

• Conduction

• Convection

• Radiation

Answer explanation

The heat from the fire causes the air in the balloon to rise. This motion pushes the balloon into the air. The more heat added, the higher it goes.

The air near the ceiling in a room is warmer than the air near the floor.

This is an example of...

• Conduction

• Convection

• Radiation

Answer explanation

Remember that in convection, heat rises and cold falls/sinks.

This is why when there is a fire, the heat rises and it is cooler/less smoky on the ground then on the ceiling.
