A Styrofoam box has a surface area of 0.20 m^2 and a wall thickness of 2.0 cm. The temperature of the inner surface is 0°C, and the outside temperature is 25°C. If it takes 2.0 hr for 5.0 kg of Si wafers to increase temperature from the initial 0°C to 10°C, determine the thermal conductivity of the Styrofoam. The molar heat capacity of bulk Si is 19.8 J/mol. K, molar mass of Si is 28.0 g/mol.
Required:
Determine the thermal conductivity of the Styrofaom.
