According to Torcelli's first barometer, the higher the mercury level in the tube is, the greater the atmospheric pressure.Is this statement true or false?
Yep. The greater the weight of air above the pool of Hg, the greater the atmospheric pressure, and the high the top of the column of Hg.
But keep in mind that Torricelli was attempting to create a vacuum, not a barometer. He observed that there was ';nothing'; above the level of the Hg in the sealed tube. Only later did he observe variations in the day-to-day heights of the column of mercury and related that to air pressure.
