why saw dust is a better insulator
than wood? - Explain,
Answers
Answer:
Sawdust are the powdery substances of wood produced by wood. They are considered as bad conductors of heat because heat travels very slowly in saw dust. It is does not allow proper mixing of oxygen and fuel. However, they are god insulators and prevents air circulation
Explanation:
Well saw dust is a better insulator than solid wood as the dust are not connected to each other so this causes the heat or cold to not get transferred properly from one end to other as the particles are not tightly packed to transfer the heat or cold. Whereas in solid wood the particles are tightly packed they allow the transfer of heat or cold easily.
One more reason is that in saw dust the medium is filled with a lot of air which is bad conductor of heat or cold
