The poorest conductor of heat is
The poorest conductor of heat is
Open in App
Solution
The correct option is D lead
- Metals are the ones which are electropositive in nature and have the tendency to lose electrons and form cations. Due to these mobile electrons, metals exhibit high conductivity towards heat and electricity.
- Examples of metals: Copper (Cu), Aluminum (Al)
- Among the given elements, Lead (Pb) is the one that exhibits the lowest conductivity towards heat.
Since Aluminum (Al), Silver (Ag), and Gold (Au) is comparatively better conductors of heat than Lead (Pb), option (A), (B), and (C) are incorrect.
Final Answer: Hence, option (D) is correct. Lead is the poorest conductor of heat.
