An aluminum sphere, initially at a temperature of 25°C, is placed in a 300°C oven. How do the temperatures of the sphere center (black) and the sphere surface (orange) change over time? Assume that the thermal conductivity of the sphere is large and that the rate of convective heat transfer to the sphere is relatively small. Why?
