A spherical apple of 8 cm diameter is to be cooled at a freezer at -12°C. Initially, the apple is at a uniform temperature of 25°C, and the heat transfer coefficient on the surfaces is 10 W/m-. °C. Determine a) The center and surface temperatures of the apple after 1 hour b) The amount of heat transfered from the apple Taking apple properties to be p = 846 kg/m', Cp = 3.82 kJ/kg · °C, k= 0.42 W/m · °C and á = 1.32 *10-7 m2/s Surrounding temperature To = -12 C
