Why does a metal bar appear hotter than a wooden bar at the same temperature? Equivalently it also appears cooler than wooden bar if they are both colder than room temperature.
(i) it is due to facts that the conductivity of metal bar is very high as of wood. So the rate of transferring the heat in metal is very large than in wood. (ii) The specific heat of metal is very low as compared to wood, so metal requires very smaller quantities of heat than wood to change each degree of temperature. So due to larger conductivity and smaller specific heat, metals become more colder when placed in colder region as compared to wood and become hotter when placed in hot region.
