Heat Transfer Quiz

What is conduction?

• Transfer of heat through sound waves

• Transfer of heat through a material by direct contact of particles

• Transfer of heat through electromagnetic waves

• Transfer of heat through fluid movement

Give an example of conduction.

• Stirring a pot of boiling water with a wooden spoon

• Blowing on a bowl of hot soup

• Putting ice in a glass of water

• Touching a metal spoon that has been sitting in a hot cup of coffee

What is convection?

• A type of cooking method

• Transfer of heat through the movement of fluids

• The transfer of heat through solid materials

• The process of converting gas to liquid

How does convection transfer heat?

• By the movement of solids

• By the movement of electromagnetic waves

• By the movement of fluids

• By the movement of gases

What is radiation?

• The movement of air from one place to another

• Transfer of heat through electromagnetic waves

• The process of converting water into steam

• A type of cooking method

Explain how radiation works in heat transfer.

• Radiation transfers heat through conduction

• Radiation transfers heat through convection

• Radiation transfers heat through chemical reactions

• Radiation transfers heat through electromagnetic waves.

What is insulation?

• Material that prevents the transfer of heat or electricity

• A type of cooking utensil

• A type of musical instrument

• A type of exercise equipment

How does insulation help in reducing heat transfer?

• Insulation traps air pockets to slow down heat transfer

• Insulation creates a direct path for heat to travel through

• Insulation increases the speed of heat transfer

• Insulation absorbs heat and releases it slowly

What is thermal conductivity?

• The ability of a material to generate electricity

• The process of converting heat into mechanical energy

• The property of a material to repel heat

• The property of a material to conduct heat

How is thermal conductivity measured?

• By measuring the color of the material

• Using a thermal conductivity meter or the formula k = (Q x L) / (A x ΔT)

• By using a ruler to measure the length of the material

• By counting the number of molecules in the material
