Question

A wooden bowl conducts less heat than a copper bowl because

• A. $k_{Wood}>k_{Copper}$
• B. $k_{Wood}\le k_{Copper}$
• C. $k_{Wood}=k_{Copper}$
• D. $k_{Wood}<k_{Copper}$

Answer 1

The correct option is D $k_{Wood}<k_{Copper}$

Thermal conductivity of wood (Non-metal) is less than the thermal conductivity of copper (metal).
$\therefore$ Copper bowl conducts heat better than wooden bowl.
