What is thermal conductivity of a bad conductor by Lee's disc method?

Answer 1

At the steady state rate of heat flowing into a system is equal to rate of heat flowing out of a system.here the rate of heat conducted by poor conductor to block below it is equated to rate of heat radiated by that block

Answer 2

This experimental method involves placing the wooden material between two specially designed discs. After ensuring the temperature across the discs is constant, one of the discs should be heated to a certain temperature, after which the heating source should be removed. Heat will move from one disc to the other but must go through the material first, which will lead to further heat loss. By measuring the difference in temperature of the two discs, it is possible to determine the thermal conductivity of the material between the discs.

Answer 3

of my think the thickness's wood cuos to bad conductor because if more thickness cous to less conductor and surface disk that if the disk circle more heat save and sent to disk 2

Answer 4

by heating the disc upto a steady state n then removing it we can measure the thermal conductivity of non metal
