Heat Flow and Conductor/Insulator Quiz

What is conduction?

• Transfer of heat through direct contact between particles of a substance

• Transfer of heat through electromagnetic waves

• Transfer of heat through sound waves

• Transfer of heat through fluid movement

Give an example of conduction in everyday life.

• Metal spoon in hot coffee

• Plastic spoon in hot coffee

• Wooden spoon in hot coffee

• Glass spoon in hot coffee

Explain the process of convection.

• Heat transfer through electromagnetic waves

• Heat transfer through direct contact

• Heat transfer through sound waves

• Heat transfer through the movement of fluids

How does radiation transfer heat?

• By conduction through direct contact

• By electromagnetic waves or photons

• By sound waves

• By gravitational waves

What is thermal conductivity?

• Ability of a material to resist electricity

• Ability of a material to change color when heated

• Inability of a material to conduct heat

• Ability of a material to conduct heat

Compare the thermal conductivity of metals and non-metals.

• Metals have higher thermal conductivity

• Non-metals have higher thermal conductivity

• Non-metals have lower thermal conductivity

• Metals and non-metals have the same thermal conductivity

Name a good insulating material and explain why it is effective.

• Aluminum

• Wood

• Copper

• Fiberglass

What are the factors that affect the insulation properties of a material?

• Age of the material, country of origin, brand, and price

• Material's conductivity, thickness, density, and temperature

• Color, smell, taste, and texture

• Material's flexibility, transparency, weight, and shape

Why are some materials good conductors of heat while others are good insulators?

• The smell of the material determines its ability to conduct or insulate heat.

• The color of the material determines its ability to conduct or insulate heat.

• The arrangement of atoms and molecules in the material determines its ability to conduct or insulate heat.

• The weight of the material determines its ability to conduct or insulate heat.

Explain how heat flows through a metal rod when one end is heated.

• Heat flows through the metal rod by evaporation.

• Heat flows through the metal rod by magnetism.

• Heat flows through the metal rod by radiation.

• Heat flows through the metal rod by conduction.
