The Hampson- (*) Linde cycle, which is used in air separation, relies on this isenthalpic effect.
In geochemistry, Wood and Spera calculated the effect of dissolved sodium chloride on this phenomenon. A constant linked with this phenomenon is theoretically equal to 2a over bR in van der Waals gases. Opthamologist Selig Percy Amoils refined a method of cataract extraction using a tool that undergoes this process at its tip. This phenomenon is quantified by a coefficient calculated as the volume times alpha T minus 1 over the heat capacity at constant pressure. Like the Boyle temperature curve, the curve visualizing this phenomenon on a temperature-pressure diagram is parabolic. The Hampson- (*) Linde cycle, which is used in air separation, relies on this isenthalpic effect. Apart from hydrogen, helium, and neon, all gases at room temperature experience the negative form of this effect, which changes sign at the inversion temperature, meaning that those gases cool as they expand. For 10 points, name this phenomenon used in many refrigerators, caused by forcibly throttling a liquid through a valve
