To what temperature must an aluminum cube placed on ice at t = 0 °C be heated so that the cube is completely immersed in it? Ignore the evaporation of water. Specific heat capacity of aluminum с=9.2 • 102 J(kg•deg), specific heat of fusion of ice l=3.35 • 105 J/kg, density of ice and aluminum, respectively, p1=0.9 g/cm3 and p2=2, 7 g/cm3.
