Find the heat conductivity of stone if 4000 g of ice is melted in one hour given that the latent heat of fusion of ice is 80 cal ⁄ gm. The slab is steam-exposed on the lower surface at a temperature of 100 ☌. Problem 1: A 10 cm thick block of ice with a temperature of 0 ☌ lies on the upper surface of 2400 cm 2 slab of stone. Where K is the thermal conductivity, q is heat transfer rate, t is the time of transfer, Q is the amount of heat transfer,A is the area of surfaced is the thickness of the body, T h is the temperature of the hot region and T c is the temperature of the cold region. The following equation can be used to calculate the rate of conduction: When it comes to conduction, the coefficient of thermal conductivity reveals that a metal body transmits heat better. The location of the molecules, however, remains unchanged. When heat is transmitted from one molecule to another by conduction, the heat energy is generally transported from one molecule to another because they are in direct touch.

Conduction can occur in solids, liquids and gases. When high-speed particles collide with slow-moving particles, the kinetic energy of the slow-moving particles increases. Thermal energy is transferred from a higher kinetic energy area to a lower kinetic energy area.
