The tomatoes (k = 0.59 W/m·K, a =0.141 * 10-6 m2/s, r = 999 kg/m3, cp = 3.99 kJ/kg·K) with an initial uniform temperature of 30°C are spherical in shape with a diameter of 8 cm. After a period of 2 h, the temperatures at the center and the surface of the tomatoes are measured to be 10.0°C and 7.1°C, respectively.
