Take two tin cans of different diameters and approximately same heights so that one can be placed into the other with some gap between them. Make a lid of thick thermocol which may cover both the cans. Make a small hole in the lid at its centre and fix a lab. thermometer in it. Fill the gap between the cans with saw dust. Now fill the inner can with hot water (~70 °C) so that water does not spring out. Cover it with a lid. Note down the temperature of water every 5 minutes till the temperature drops to about 50 °C. Record the readings. Repeat the experiment by using common slat, sand, iron dust in place of saw dust. Plot cooling curves for all the four cases. Which of these materials is the best thermal insulator and which one is worst thermal insulator.
