Heat Transfer Quiz

What is heat transfer?

• The movement of kinetic energy from one object to another

• The movement of electrical energy from one object to another

• The movement of thermal energy from one object or system to another due to a difference in temperature.

• The movement of sound energy from one object to another

Which process of heat transfer occurs through direct contact?

• Convection

• Evaporation

• Radiation

• Conduction

Which process of heat transfer occurs in fluids?

• evaporation

• radiation

• conduction

• convection

Which process of heat transfer does not require a medium?

• convection

What is conduction?

• The transfer of heat or electricity through a substance without any apparent movement of the substance itself.

• The transfer of heat or electricity through a substance by the movement of the substance itself.

• The transfer of heat or electricity through a substance by the absorption of the substance.

• The transfer of heat or electricity through a substance by the emission of the substance.

What is convection?

• The process of heat transfer through the movement of a fluid caused by differences in temperature.

• The process of heat transfer through the movement of a solid caused by differences in temperature.

• The process of heat transfer through the movement of a gas caused by differences in pressure.

• The process of heat transfer through the movement of a fluid caused by differences in density.

What is radiation?

• Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles.

• Radiation is the absorption of energy by sound waves or by moving subatomic particles.

• Radiation is the emission of energy as sound waves or as stationary subatomic particles.

• Radiation is the absorption of energy by electromagnetic waves or by stationary subatomic particles.

Give an example of conduction.

• When you hear a song and the melody is transferred to your brain.

• When you see a rainbow and the colors are transferred to your eyes.

• When you smell a flower and the scent is transferred to your nose.

• When you touch a hot pan and the heat is transferred from the pan to your hand.
