"WebAug 14, 2024 · Boyle used a J-shaped tube partially filled with mercury, as shown in Figure 5.3.1. In these experiments, a small amount of a gas or air is trapped above the mercury column, and its volume is measured at atmospheric pressure and constant temperature. More mercury is then poured into the open arm to increase the pressure on the gas sample. " - Expanding gas experiment
