Slow Physics: Recording the Ascent and Descent of a Water Column
Lindén, Johan; Källman, Kjell-Mikael; Holm, Erik
Physics Education, v53 n4 Article 045003 Jul 2018
A glass filled with carbon dioxide gas upside down on a plate of water constitutes an excellent demonstration of the solubility of gases. If the water level on the plate is maintained the CO[subscript 2] will slowly dissolve and the column of water will rise inside the glass, without quite reaching the ceiling, before an opposite process sets in: the water level will even more slowly begin to sink in a process which will take several years. We followed the process for several months, recording images of the water column with 10min to 1h intervals. The physics of the process is discussed and modeled quantitatively.
