A slab of aluminum of area 2m^2 and with a mass 9 kg is lying on some insulation on the surface of the moon during daytime and is equilibrated at a temperature To= 140 degrees C. A shadow from a spacecraft that lands nearby suddenly cuts off the sun. How much does the temperature of the aluminum drop during the first minute ? Assume E=0.8 , and assume the outgoing heat flux is constant and determined by temperature To.
