A small pond of depth 0.5 m deep is exposed to a cold winter with outside temperature of 263 K . Thermal conductivity of ice is K=2.2 Wm ⁻¹ ~K ⁻¹ , latent heat L=3.4 10^5 Jkg ⁻¹ anTwo identical rods made of two different metals A and B with thermal conductivities K_ A and K_ B respectively are joined end to end. The free end of A is kept at a temperature T₁ A steel cooking pan has copper coating at its bottom. The thickness of copper coating is half the thickness of steel bottom. The conductivity of copper is three times that of steelTwo identical rooms in a house are connected by an open doorway. The temperatures in the two rooms are maintained at two different values. Therefore,A metallic wire of length l is held between two supports under some tension. The wire is cooled through ^ . Let Y be the Young's modulus, the density and the thermal coefficient ofA sphere and a cube having equal surface area are made of the same material. The two are heated to the same temperature and kept in identical surrounding. The ratio of their initiaConsider a composite slab consisting of two different materials having equal thickness and equal area of cross-section. The thermal conductivities are K and 2 K respectively.
