Question

Which metal has the lowest thermal conductivity?

Hint:

Best conductors: Silver (\(\text{Ag}\)) and Copper (\(\text{Cu}\)). Poorest conductors: Lead (\(\text{Pb}\)) and Mercury (\(\text{Hg}\)).

Answer 1

Step 1: Understanding the Concept:
Thermal conductivity is the ability of a material to conduct heat.
While metals are generally good conductors, some are significantly poorer than others.

Step 2: Detailed Explanation:
Silver and Copper are among the best metallic conductors of heat.
In standard high school curricula, Lead (along with Bismuth) is frequently cited as the classic example of a metal with exceptionally low thermal and electrical conductivity.

Step 3: Final Answer:
Lead is generally considered to have the lowest thermal conductivity among common metals.
