Heat Transfer

Q1: What is the thermal conductivity of a perfect heat insulator ?

A zero

B one

C ∞

D between 0 and ∞

ANS:A - zero

The thermal conductivity of a perfect heat insulator is effectively zero. This means that it has extremely low thermal conductivity, and therefore, it does not allow the transfer of heat through it. Heat insulators are designed to minimize heat transfer by reducing thermal conductivity, thereby maintaining temperature differentials across the insulating material.
