Question

Which is the least conductor of heat?

Answer 1

• Metals seem to be the most conductive materials, while insulators (ceramics, wood, and plastics) are the least.
• The lead conductor of heat is lead.
• Lead $\left(\mathrm{Pb}\right)$ is a highly malleable white shiny metal with a soft texture.
• Lead is particularly bad at conducting heat because it quickly interacts with the atmosphere to generate lead oxide.
• As a consequence, lead is the least heat conductor.
