Liquid helium is stored at its boiling-point temperature of 4.2k
in a spherical container (r = 0.404 m). the container isa
perfect blackbody radiator. the container is surrounded by
aspherical shield whose temperature is 86.8 k. a vacuum exists
inthe space between the container and shield. the latent heat
ofvaporization for helium is 2.1 x 104 j/kg. what mass
ofliquid helium boils away through the venting valve in
15.5hours?
