A hollow spherical iron container whose outer diameter is 20 cm and the thickness is 0.4 cm is filled with ice water at 0 degree C. If the outer surface temperature is 5 degree C, determine the approximate rate of heat loss from the sphere and the rate at which ice melts in the container. Draw the process diagram.
