Two materials of different materials are identical in size and wall thickness. They are filled with equal amount of ice at 0 degree celsius. If the ice melts completely in 10 and 25 minutes resp., compare the coefficient of thermal conductivity of the materials of the vessel.

Let us say, for example, we have two vessels copper and Iron. Copper vessel would melt down the ice faster than the iron vessel. Thermal conductivities of copper and iron are 213 and 32 resp. Thermal conduictivity is the quantity of heat transmitted, due to unit temperature gradient, in unit time under steady conditions.
