A student is trying to boil an egg for the breakfast. An ordinary egg can be approximated as a 5- cm diameter sphere. The egg is taken directly from the refrigerator initially at a uniform temperature of 10°C and is dropped into a sealed pot of water which boils under 100 kPa constant pressure with a quality factor of 0.25 at that exact moment. After a while without the heating from the stove, the temperature of the egg rises to 80°C by the hot water. Taking the density and specific heat of the egg to be p = 1020 kg/m³ and c = 3.32 kJ/kg-°C. Draw a schematic and list necessary assumptions. Determine how much heat is transferred to the egg. Determine the minimum amount of water in order for the egg to reach 80°C.
