The coma chemistry model uses the Knudsen layer to describe regions near the site of this process. The optimal setup parameters of two chambers of a device that promotes this process are described by the rule of 20. Catastrophic BLEVEs (“B-L-E-V-E’s”) can occur when a large amount of material undergoes this process at once during an adiabatic flash. (-5[1])An empirical rule describing this process states that its entropy is roughly 10.5 times the ideal gas constant. Energetic forms of this process can be stabilized by adding bumping chips to a sample. (10[1])This process can be encouraged by spinning samples in a vacuum through a heat bath in rotovaps. For 10 points, name this phase transition (10[1])that occurs at different temperatures for each component of a mixture during distillation. ■END■ (10[7])
