Question
A slab of stone of area 0.36 m2 and thickness 0.1 m is exposed on the lower surface to steam at100oC. A block of ice at 0oC rests on the upper surface of the slab. In one hour 4.8 kg of ice is melted. The thermal conductivity of slab is (Given latent heat of fusion of ice = 3.36 × 105 J kg-1)
