At a pressure of 1 atmosphere a column of mercury in a barometer is supported to the height h = 0.76 m.The density of mercury is 13.6 × 10³ kg/m³.A barometer of similar design filled with water would support a column of water how high at a pressure of 1 atmosphere? A)the same height h B)about 1.36h C)less than one tenth h D)more than ten times h

The height of the liquid column in a barometer is inversely proportional to the density of the liquid. Since water is much less dense than mercury, a water barometer would support a column of water much higher than the mercury column to exert the same pressure.
