The poorest conductor of heat among the following is : Join @Apnapdfs

Explanation

## Page 8 Any substance through which heat does not flow is called a poor conductor (insulator); e.g., wood, glass, etc. All metals are good conductors of heat, but compared to other metals, lead and mercury have relatively low (poor) thermal conductivity. The thermal conductivity of lead is about 34.7 W/mK, whereas the thermal conductivity of mercury is about 8.3 W/mK.
