A very long, narrow tube is sealed at one end, and is immersed in a fluid so that it fills up completely. The closed end of the tube is then lifted up out of the fluid, while the open end is kept submerged. Three hypothetical scenarios are shown. What will happen to the fluid level in each scenario?
1) The fluid level will remain the same in all scenarios.
2) The fluid level will rise in all scenarios.
3) The fluid level will decrease in all scenarios.
4) The fluid level will rise in scenario 1, remain the same in scenario 2, and decrease in scenario 3.
5) The fluid level will decrease in scenario 1, remain the same in scenario 2, and rise in scenario 3.
