Imagine a $1$ meter airtight cube at room temperature with a large bucket of water in it.
What would would happen if you removed all the atmosphere?
I know the water would evaporate, but eventually wouldn't the evaporated water raise the air pressure so the water no longer evaporates?
Since the water is at room temperature I would think the water in the air would condensate, but the water condensing would also lower the air pressure.
How would this actually work?
