A 120 mm diameter apple (density = 990 kg/m3, cp = 4170 J/kg.C,k = 0.58 W/m.C), approximately spherical in shape is taken from a25 C. environment and placed in a refrigerator where temperature is6 C and average convective heat transfer coefficient over the appleis 12.8 W/m2.C. Determine the temp at the center of the apple aftera period of 2 hours
