Would you expect a dynamic equilibrium in a liquid in an open container?
We consider the equilibrium phase change, say...
And this is generally a function of temperature....water for instance at a given temperature exerts a equilibrium vapour pressure, at
Now in an open container, the liquid water (or other liquid) will slowly evaporate, and the container will empty eventually. In a closed container, there is dynamic equilibrium between the vapour phase, and the liquid phase, and the rate of evaporation is equal to the rate of condensation.
Of course for water,
