As thermal condutivity of silver is more than sawdust and thermal conductivity of saw dust is more than thermocol, arrangement is like this..

Thermal flask, outside silver paper, outside saw dust and finally thermocol.

The materials shall be placed in increasing order of their convective heat
transfer coefficient viz thermocol, saw dust, and then steel, which has the
highest heat transfer coefficient.


Please tell me if i am wrong.

We need a material which has got lowest thermal conductance inside, which is in contact with the boiled water..so from inside first come silver paper, thermocol sawdust.
