Question

How do substances with high thermal conductivity affect the transfer of thermal energy?

A. They slow down the transfer of thermal energy.
B. They have no effect on thermal energy transfer.
C. They speed up the transfer of thermal energy.
D. They create thermal energy.

Answer 1

Substances with high thermal conductivity speed up the transfer of thermal energy.

Step-by-step explanation:

Substances with high thermal conductivity actually speed up the transfer of thermal energy.

In general, good conductors of electricity like metals (e.g. copper, aluminum, gold, silver) are also good heat conductors.

When substances with high thermal conductivity come into contact with a substance of lower temperature, the energy is transferred from the hotter substance to the colder substance, resulting in a faster transfer of thermal energy.
