A space probe is fitted with a metallic heat shield to protect it from the extreme temperatures of space. This shield has a thickness of 0.6 cm, a surface area of 295 cm², and a thermal conductivity of 18 W/m °C. The shield's function is to dissipate the heat absorbed from solar radiation, which amounts to an intensity of 1350 W. The outer surface of the shield loses heat to the surrounding space, assumed to be at a temperature of 19°C, by convection. The convection heat transfer coefficient is given as 78 W/m².°C. For the purposes of this problem, disregard any heat loss by radiation. Your task is to formulate an expression for the variation of temperature in the heat shield. Additionally, estimate the temperatures at the inner and outer surfaces of the shield. Understanding these temperatures is vital to ensure the shield can adequately protect the probe's delicate instruments from the harsh thermal environment of space.
