The flask has silvered outer and inner cylindrical walls to reduce radiation heating, Store one liter of Ne(l) in a Dewar flask at its boiling point,27.1k and the total emissivity of silver is 0.02. Assuming that radiation transfer among the walls is the only energy transfer that occurs, calculate the rate of Ne(l) vaporization in g/hr. The outer wall is at 300K. The enthalpy of vaporization of Ne (l) is 8.70 * 10^4J/kg. The inner wall is a 10cmdiameter cylinder and one may assume that the Dewar flask has a flat bottom and the top surface of the Ne(l) does not intercept any radiation.
