An apple with the following properties ( weight= 2.7 N, Diameter=0.0921 m, Volume=0.000325 m^3) is cooled to a uniform temperature of 3 degrees C. The apple is then expossed to open air at a temperature of 24.8 degrees C. After 5 minutes the center of the apple is 3.1 degrees C and the surface of the apple is 8.4 degrees C. What is the heat transfer coefficient of the apple? Also, calculate the thermal diffusivity and thermal conductivity.
