3. A metal cylinder is placed upright on horizontal top of an ice slab of temperature 0 °C. Initial temperature of the cylinder is 50 °C. The vertical curved surface and top of the cylinder are adiabatic while its base is perfectly conducting. Ice below the base of the cylinder melts and the cylinder sinks into the hole thus formed. What fraction of height of the cylinder will ultimately sink? Specific heat of material of cylinder is 400 J/(kg°C) and density is 9.0 g/cm³. Specific latent heat of melting of ice is 4.0×105 J/kg and density is 0.9 g/cm³. Neglect dip in melting point of ice due to increase in pressure. (а) 30% (b) 50% (b) 40% (c) 60%
