A 10 cm diameter copper ball is to be heated from 100°C to an average temperature of 150°C in 30 minutes. Taking the average density and specific heat of copper in this temperature range to be p = 8950 kg and C, = 0.395 kJ kg. °C respectively, determine the total amount of heat transfer to the copper ball, the ayerage rate of heat transfer to the ball and the average heat m3 flux.
