Argon saturation responses

Figure 1 Vector diagram of helium and argon saturation changes in response to upper ocean processes.

Two chemically saturated particles, such as two molecules of methane or two atoms of argon, are subject to attractive forces as they approach one another. The intermolecular forces are electrical in origin since they are responsible for the phenomena of gas imperfection and liquefaction, they are often called van der Waals forces. The energy of vaporization of a liquid provides a convenient measure of the strength of these forces, since it is the energy required to pull the molecules from the liquid, where they are in proximity, and bring them into the gas where they are widely separated. The energy of vaporization is simply related to the heat of vaporization of the liquid at constant pressure ... 

Figure 2. Effect of oxygen in the photovoltaic response of the platinized Chi a electrode, (a) Electrolyte purged with argon gas, measurements made under a positive pressure of Ar (b) O, electrolyte saturated with oxygen (c) , oxygen removed by passage of argon gas through the electrolyte solution for 30 min. The ordinate units are given in 10 electrons per incident photon. The efficiency of the liquid junction cell was calculated by dividing the photovoltaic response (electrons sec ) by the incident photoresponse (photons sec ).
