A 5cm diameter copper sphere (of density = 8954 kg/m3, specific heat capacity = 0.3831 kJ/kg K) is initially at a uniform temper

ature of 10oC. The sphere is placed inside an environment having a temperature of 200oC. The surface heat transfer coefficient is h = 10 W/(m2K). Under these conditions, we can assume uniform internal temperature for the sphere. What is the temperature inside the sphere after 10 minutes in this environment?
