There are two beakers in a sealed container at room temperature. One
contains a liter of H2O, the other a liter of alcohol. The two
liquids maintain different vapor pressures. But since vapor pressure
is a dynamic process where evaporation equals condensation, the
question arises, "What will happen over a long period of time?"
some answers I have heard...
1)the two liquids will mix in equal quantities in the beakers
2)they will mix in equal quantities in the beakers and on the floor
of the container
3)they will mix in the beakers in some proportion determined by v.p.
4)one liquid will move to the other beaker, leaving a beaker dry
5)nothing - (once v.p. is established the system is in a stable state)
Please justify any answers. Also what effect might changing the
temperature or liquids used have?
