This question starts by stating.. "a U-shaped tube filled with water is closed on one end. Tube is about 1m tall. When water is removed from the open end, the water level in the closed end doesnt change.."
Then a series of questions..
My question is, why doesnt the water levels equal each other on each end, after you remove the amount of water?
I know its a matter of atms acting on the water, but cant understand how that works.
any help is really appreciated.
