Heat Transfer: Conduction

What is conduction?

• Transfer of heat through sound waves

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

• Transfer of heat through fluid movement

• Transfer of heat through electromagnetic waves

Give an example of conduction in everyday life.

• Wearing a hat in the winter

• Blowing on hot soup to cool it down

• Using a microwave to heat up food

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

How does conduction transfer heat?

• By direct contact between particles

• By radiation

• By convection

• By sound waves

What materials are good conductors of heat?

• Metals

• Plastic

• Wood

• Glass

What materials are poor conductors of heat?

• Insulators

• Metals

• Conductors

• Wood

How does the thickness of a material affect conduction?

• It affects the rate at which heat can transfer through the material.

• It decreases the rate of conduction

• It increases the rate of conduction

• It has no effect on conduction

What is the difference between conduction and convection?

• Conduction is the transfer of heat through radiation, while convection is the transfer of heat through direct contact.

• Conduction is the transfer of heat through the movement of solids, while convection is the transfer of heat through the movement of fluids.

• Conduction is the transfer of heat through direct contact, while convection is the transfer of heat through the movement of fluids (liquids or gases).

• Conduction is the transfer of heat through the movement of fluids, while convection is the transfer of heat through direct contact.
