A 10 cm diameter aluminum ball is to be heated from 94°C to anaverage temperature of 140°C in 30 minutes. Taking the averagedensity and specific heat of aluminum in this temperature range tobe 2,700 kg/m3 and Cp = 0.91 kJ/kg-K, respectively,determine the ff: (Round off your final answers to two (2) decimalplaces.)
(a) the total amount of heat transferred to the ball in kJ=
(b) the average heat transfer rate to the aluminum ball in W=
(c) the average heat flux in W/m2
