Consider an insulated container containing 2.56-kg ice at -11°c. Inside the container, there is a spherical object with radius 36 cm and at a certain temperature of 14396°c. Calculate the time (in hours) where all the ice has melter. Assume that sphere is a black body. Use the following: pi 3.14 water 4190 J/kgk, c_ice 2100 J/kgK, Lf= 334,000 J/kg, a 5.6704e (-8) W/m²K4.

Transcribed Image Text:Consider an insulated container containing 2.56-kg ice at -11°c. Inside the container, there is a spherical object with radius 36 cm and at a certain temperature of 14396°C.
Calculate the time (in hours) where all the ice has melter. Assume that sphere is a black body.
Use the following:
pi= 3.14
c_water = 4190 J/kgk, c_ice = 2100 J/kgK, Lf = 334,000 J/kg, o = 5.6704e (-8) W/m²K4.
Final answer in TWO decimal places.
