Question

Name the best conductor of heat.

Answer 1

Hint: You may first recall the definition of thermal conduction as the material’s ability for heat conduction. You could think of the core mechanism in the material that qualifies the material to be the best conductor. You could also mention the commonly used material for applications that require best thermal conduction.

Complete step by step answer:
In the question we are asked to name the best conductor of heat. You may wonder what that property of a material is that qualifies it to be the best conductor. Very good mobility of the electrons in a material qualifies it to be a best conductor. Metals are that class of materials that are known for their electric as well as thermal conductivity.
Silver is found to be the best in that class. Be it electric or thermal conduction, silver tops as best conductor in both. Thermal conduction value of silver metal is found to be$430 w/mK$.

Additional information:
Gold and copper are also classified as good conductors. However, copper being cheap is preferred over silver for basic applications. Most of the kitchen utensils are made of copper and the electric wires are also made of copper.

Note: Heat conductivity is a significant property in determining the material’s specific application. Heat exchangers, heat sinks and cookwares are the applications that require good thermal conduction property. Also, for any application, materials with considerable quality and best availability at less expense are preferred.
