What is conduction?

• The transfer of heat through a fluid.

• The transfer of heat through electromagnetic waves.

• The transfer of heat through or along a material (one molecule to the next).

• The transfer of heat through a vacuum.

Which of the following is an example of conduction?

• Still air

What can bad thermal conductors be used as?

• Conductors

• Insulators

• Semiconductors

• Superconductors

According to the principles of heat, what is the relationship between the speed of heat travel and the conductivity of a material?

• The slower the heat travels, the better the conductor

• The faster the heat travels, the better the conductor

• The speed of heat travel does not affect conductivity

• The speed of heat travel is inversely proportional to conductivity
