Heat Conductivity: Melting on Metal vs Wood — xmdemo 081

The aluminum block is NOT colder than the piece of wood.

It FEELS cold to warm blooded mammals like us because heat is conducted from us into the aluminium block faster than if it were a piece of wood. Our sense of hotness/coldness is not based on actual temperature. Instead, it is based on the RATE (and direction) of heat transfer!

If there were a specie of humans whose body temperature were lower than room temperature, the aluminium block would feel hotter to them because heat will be conducted from the metal into them at a faster rate than if it were a piece of wood.
