density of mercury - Students Free Notes

If a liquid has twice the density of mercury, what will be the height of the liquid column in a barometer?

In a barometer, the height of the liquid column is determined by the balance between the weight of the liquid column and the atmospheric pressure. The relationship between the height of the liquid column and the density of the liquid is given by the following equation: P=ρgh Where: P is the atmospheric pressure, ρ\rho is … Read more
