Step 1
Step 1: The pressure is given by the formula: $$P = \rho g h$$ where $\rho$ is the density of mercury, $g$ is the acceleration due to gravity, and $h$ is the height of the mercury column. Show more…

As a storm front moves in, you notice that the column of mercury in a barometer rises to only $736 \mathrm{~mm}$. What is the air pressure in $\mathrm{kPa}$ ?
As a storm front moves in, you notice that the column of mercury in a barometer rises to only 736 mm. (a) What is the air pressure? (b) If the mercury in this barometer is replaced with water, to what height does the column of water rise? Assume the same air pressure found in part (a).
As a thunderstorm passes through a region, there is an associated drop in atmospheric pressure. If the height of a mercury barometer drops by 27.3 mm from the normal height, what is the atmospheric pressure (in Pa)? Normal atmospheric pressure is 1.013 Ă— 10^5 Pa and the density of mercury is 13.6 g/cm^3. Answer should be in Pa.
