Reef Chemistry Question of the Day #216
Imagine you have a long glass tube, sealed at one end. You fill it with various liquids, and invert it with the open end facing down into a bowl of the same liquid, and the closed end straight up, without allowing any gas to enter.
In each case, the top of the liquid drops down from the end of the closed tube and stabilizes some way down the tube, leaving a gas/vacuum space between the top of the liquid and the sealed end of the tube. I'll call this the "gas gap".
Using the fluids below, rank order them from the one with the smallest gas gap at the top to the one with the largest gas gap.
A. Vodka < Tap water < Seawater < Mercury
B. Mercury< Tap water < Seawater < Vodka
C. Vodka < Seawater < Tap Water < Mercury
D. Mercury< Vodka < Seawater < Tap Water
E. Mercury < Seawater < Tap Water < Vodka
Good luck!
