Knowledge Check: Heat Transfer

What is heat defined as?

• The transfer of energy from one object to another (hotter to cooler)

• The transfer of energy from one object to another (cooler to hotter)

• The transfer of mass from one object to another (hotter to cooler)

• The transfer of mass from one object to another (cooler to hotter)

In how many different ways is heat transferred?

• One

• Two

• Three

• Four

Which method of heat transfer does not require a medium (can occur in a vacuum)?

• Radiation

• Conduction

• Convection

• Conduction and Convection

What is the main difference between conduction and convection?

• Conduction occurs in fluids, while convection occurs in solids.

• Conduction involves the transfer of heat through a solid material, while convection involves the transfer of heat through fluids.

• Conduction requires a medium, while convection does not.

• Conduction involves electromagnetic waves, while convection involves particle movement.
