If you could somehow replace the mercury in a mercury barometer with a denser liquid, would the height of the liquid column be greater than or less than the height of the mercury? Why?
Solution: Therefore, it depends on how much you put in there. But in general, the density of liquid is inversely proportional to the specific volume. The denser the liquid, the less volume it will have and because the diameter of the tube will not change, the height will. So the height will be less than that of the mercury. d = density v = specific volume v = 1/d
