6. A cube of ice (density=8000kg/m^3, specific heat capacity = 470J/Kg-K) is heated to a high temperature and is palced on a block of ice at 0^0 C.The cube melts the ice below it , displaces the water and sinks.In the final equilibrium position , its upper surface just goes inside the ice.Calculate the initial temperature of the cube.Neglect any loss of heat outside the ice and the cube. The density of the ice =900 kg/m^3 and the latent heat of fusion of ice=3.36 x 10^5J/kg7.1kg of ice at 00 C is mixed with 1kg of ice at 1000 C .What will be the composition of the system when the thermal equilibrium is reached?Latent heat of fusion of ice=3.36 x 10^5 J/kg and latent heat of vapourisation of water= 2.26 x 10^6J/kg
