Consider an insulated container containing 1.63-kg ice at -18°C. Inside the container, there is a spherical object with radius 37 cm and at a certain temperature of 15162°C. Calculate the time (in hours) where all the ice has melter. Assume that sphere is a black body. NOTE: Use pi = 3.14 Final answer in TWO decimal place. No need to type the unit. c_water = 4190 J/kgk, c_ice = 2100 J/kgK, Lf = 334,000 J/kg, o = 5.6704e(-8) W/m²K4. Round your answer to 2 decimal places.
