Siphonic Concepts Examined: A Carbon Dioxide Gas Siphon and Siphons in Vacuum
Ramette, Joshua J.; Ramette, Richard W.
Physics Education, v46 n4 p412-416 Jul 2011
Misconceptions of siphon action include assumptions that intermolecular attractions play a key role and that siphons will operate in a vacuum. These are belied by the siphoning of gaseous carbon dioxide and behaviour of siphons under reduced pressure. These procedures are suitable for classroom demonstrations. The principles of siphon action are summarized. (Contains 2 figures.)
