3. Imagine you are measuring air pressure of an open areausing an apparatus looking like the one on the right: A longglass tube, sealed at one end, has an inner diameter of 10.0mm. You consider choosing a liquid between mercury andwater to fill this apparatus to measure air pressure. (densityof Hg = 13.6 g/mL, density of water = 1.00 g/mL)a) If the atmospheric pressure is 1.1 atm, how high (inmeters) is the column of mercury in the tube?b) If you fill this apparatus with water, how high is the column of water in the tube?c) Based on your answer to a) and b), explain why mercury is a better option tomeasure air pressure than water.
