Question

A simple demonstration of conduction can be achieved with a Bunsen burner and some rods of different materials (copper, iron and glass are good materials to try).

Melt some candle wax and dip the end of each rod into it; use the melted wax to stick a small nail or a pin to the end of each rod. Put the rods on a tripod and place the ends without candle wax into a Bunsen burner flame. The nail on the end of the best conductor will fall off first. In which order do you expect the nails to fall?

Accepted Answer

Coppers's coefficient of thermal conductivity is greater than the coefficient of thermal conductivity of iron. And the coefficient of thermal conductivity of glass is least of all. Thus, the rate of transfer of heat in the copper is fastest and in the glass it will be slowest of all the three. Hence, the nail in copper will fall at earliest then the one in iron and in the end the glass one.
