Задача id12775

An iron ball with a radius of 1 cm, heated to 393° K, is placed on ice. To what depth will the ball sink into the ice if the specific heat of iron is c = 475 J/kg deg? Ice density p0 = 900 kg/m3. The density of iron is p = 7.9 103 kg/m3. Ice temperature 273°K; specific heat of fusion R = 3.34·105 J/kg. Neglect the thermal conductivity of ice and heating of water.
