Heat Transfer Quiz

What is conduction?

• The transfer of heat through radiation

• The process of transferring heat through the movement of a solid

• Transfer of heat through a material without the material itself moving

• The process of transferring heat through the movement of a fluid

Give an example of conduction.

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

• Putting ice in a glass of water

• Blowing on a bowl of hot soup

• Stirring a pot of boiling water with a wooden spoon

What is convection?

• Transfer of heat through the movement of gases

• Transfer of heat through the movement of fluids

• Transfer of heat through the movement of solids

• Transfer of heat through electromagnetic waves

Give an example of convection.

• Lighting a candle

• Freezing water in the freezer

• Baking a cake in the oven

• Boiling water in a pot

What is radiation?

• A type of cooking method

• The process of converting water into steam

• Transfer of heat through electromagnetic waves

• The movement of hot air from one place to another

Give an example of radiation.

• Lightning during a thunderstorm

• Boiling water on a stove

• The heat from the sun reaching the Earth

• Microwaves heating food

What is insulation and how does it work?

• Insulation is a type of fabric that absorbs heat and releases it slowly.

• Insulation is a type of liquid that evaporates when exposed to heat.

• Insulation is a type of metal that conducts heat very well.

• Insulation is a material that reduces the transfer of heat by trapping air pockets within its structure.

How does insulation help in conserving energy?

• By attracting more heat to the building.

• By reducing the transfer of heat between the inside and outside of a building.

• By creating a barrier that allows heat to escape easily.

• By increasing the transfer of heat between the inside and outside of a building.
