We’re being asked to determine the pressure of a gas using an open-end manometer.
A manometer allows you to determine the pressure of a gas (Pgas) sample by using the atmospheric pressure (Patm) and the difference in the height of mercury (h).
Different conditions for an open-end manometer are illustrated below:
• When Pgas is pushing the same force as Patm
• When Pgas is pushing harder than Patm
If the atmospheric pressure is 0.980 atm , what is the pressure of the enclosed gas in each of the three cases depicted in the drawing ?
What is the pressure of the enclosed gas in (ii)? Assume that the gray liquid is mercury.
