A thin-walled, spherical metal container is used to store liquid nitrogen at 77 K. The container has a diameter of 0.46 m and thickness of 0.09 m. The external surface is exposed to ambient air at 300 K and the thermal conductivity of the metal is known to be k = 50.2 W/m*K. Calculate the thermal resistance, in K/W, of the spherical container under this conditions of temperature. Correct your answer to three significant figures (use scientific notation if needed).
