Packet 12: Bonus 13

These objects drive the L/T transition in brown dwarfs, since they sink below the photosphere at temperatures below 1700 Kelvin. For 10 points each:
[10m] Name these objects whose formation in supersaturated environments is described by Köhler (“KOOL-er”) theory. On Earth, silver iodide can be used to “seed” these objects.
ANSWER: clouds [accept cloud seeding]
[10e] Köhler theory predicts that clouds form when the relative form of this quantity is greater than 100 percent. This quantity is the concentration of water vapor in air.
ANSWER: humidity [accept relative humidity]
[10h] When air is supersaturated, clouds can form via the heterogeneous form of this process, in which water vapor condenses onto CCNs like salt crystals and aerosols.
ANSWER: nucleation [accept heterogeneous nucleation]
