Liquid oxygen is stored in a thin-walled, spherical container 0.8 m in diameter, which is enclosed within a second thin-walled, spherical container 1.2 m in diameter. the opaque, diffuse, gray container surfaces have an emissivity of 0.05 and are separated by an evacuated space. if the outer surface is at 275 k and the inner surface is at 95 k, what is the mass rate of oxygen lost due to evaporation, in kg/s? (the latent heat of vaporization of oxygen is 2.13 x 105 j/kg.)

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
