1A 15-cm-diameter aluminum ball is to be heated from 80°C to an average temperature of 200°C. Taking the average density and specific heat of aluminum in this temperature range to be 2700 kg/m3 and Cp = 0.90 kJ/kg · °C, respectively, determine the amount of energy that needs to be transferred to the aluminum ball.
