(b) In an open-end manometer, the left (reference) arm is open to the atmosphere (P ≈ 1 atm), and the difference in the heights of the two columns gives the difference between atmospheric pressure and the pressure…

The major mechanisms that drive pulmonary ventilation are atmospheric pressure (Patm); the air pressure within the alveoli, called alveolar pressure (Palv); and the pressure within the pleural cavity, called intrapleural pressure (Pip).

It covers how barometers measure pressure, noting that sea level pressure is 760 mm Hg, which decreases with altitude, such as to 253 mm Hg on Mount Everest. This reduction impacts oxygen availability, necessitating supplemental oxygen for climbers. Understanding these pressure dynamics is vital for accurate weather predictions.

It highlights the need to correct for water vapor using Dalton's law to find the gas's true pressure, combining atmospheric pressure and water vapor pressure at the reaction temperature. An example is provided to demonstrate the calculation of dry hydrogen gas volume at STP using these concepts.
