"When Robert Boyle conducted his experiments, he calculated the pressure in inches of mercury. On a day when the atmospheric pressure was29.85 in Hg, he trapped some air in the tip of a J-tube and calculated the difference in the height of the mercury in the two arms of the tube (h). Boyle added additional mercury and the level rose in both arms of the tube so that h=30.0 inches when h=12.0 inches, the height of the gas in the tip of the tube was 32.00 in.
1. Determine what was the height of the air space in tip of the tube after the additional mercury was added?
2. Determine the pressure of the gas in the tube before and after the additional mercury in the Hg?
