Many tongues have been injured by licking a piece of metal on a very cold day. Why would no harm result if a clean piece of wood were licked on the same day?
Step 1 of 3
Solution 10E A metal is a good conductor of heat. For this reason, it can absorb and leave heat very fast. On a very cold day, the metal piece remains very cold too as it loses its heat fast to the atmosphere. So, if it is licked with a tongue, the tongue will lose its heat fast to the metal and reaches a very low temperature. This way, the tongue can be injured. The wood is a bad conductor of heat. So, it will not be able to absorb heat from your tongue as efficiently as a metal. The process of heat absorption by the wood would be very slow. So, the tongue temperature does not come down drastically and hence it is not injured.
