Liquid nitrogen is stored at its boiling point temperature of -196 °C in a vacuum flask. The flask consists of two containers, one within the other, with vacuum in between. The inner flask has a surface area of 0.2 m? and can be considered a perfect blackbody. At what temperature should the surface of the outer container (also a perfect blackbody) be maintained to limit the evaporation rate of Nitrogen to 430 grams per hour? The latent heat of vaporisation of liquid Nitrogen is 200 kJ/kg. O 77 °C O -148 °C O 215 °C -58 °C O 244 °C Liquid nitrogen is stored at its boiling point temperature of -196 °C in a vacuum flask.
