Question
Normal atmospheric pressure is $1.013 \times 10^{5}$ Pa. The approach of a storm causes the height of a mercury barometer to drop by $20.0 \mathrm{mm}$ from the normal height. What is the atmospheric pressure?
Step 1
Given: Height drop = 20.0 mm To convert from millimeters to meters, divide by 1000. Height drop = 20.0 mm / 1000 = 0.020 m Show more…

Normal atmospheric pressure is $1.013 \times 10^{5}$ Pa. The approach of a storm causes the height of a mercury barometer to drop by 20.0 $\mathrm{mm}$ from the normal height. What is the atmospheric pressure? (The density of mercury is $13.59 \mathrm{g} / \mathrm{cm}^{3} . )$
Normal atmospheric pressure is $1.013 \times 10^{5} \mathrm{Pa}$. The approach of a storm causes the height of a mercury barometer to drop by $20.0 \mathrm{mm}$ from the normal height. What is the atmospheric pressure? (The density of mercury is $\left.13.59 \mathrm{g} / \mathrm{cm}^{3} .\right)$
What is the pressure inside the drop of mercury of radius $3.00 \mathrm{~mm}$ at room temperature ? Surface tension of mercury at that temperature $\left(20^{\circ} \mathrm{C}\right)$ is $4.65 \times$ $10^{-1} \mathrm{~N} \mathrm{~m}^{-1}$. The atmospheric pressure is $1.01 \times 10^{5} \mathrm{~Pa}$. Also give the excess pressure inside the drop.
