Consider a fully ionized hydrogen plasma in a gravitational field in planar geometry. You may assume that both the protons and electrons each have an ideal, non-degenerate equation of state. 1. Argue that in the absence of an electric field, the protons would sink to the bottom of the atmosphere.

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.
