Key Concepts

Pressure Units

Pressure is a measure of force applied per unit area and can be expressed in various units, including inches of mercury (in Hg), pascals (Pa), and atmospheres (atm). Understanding how to convert between these units is essential for solving pressure-related problems in chemistry and physics.

Conversion Factors

Conversion factors are ratios that express how many of one unit are equal to another unit. For example, 1 in Hg is equivalent to 3,386.39 Pa. Using these factors allows for the accurate transformation of measurements from one unit to another, which is crucial in calculations involving pressure.

Atmospheric Pressure

Atmospheric pressure is the pressure exerted by the weight of the atmosphere above a given point. At sea level, standard atmospheric pressure is defined as 101,325 Pa or 760 mm Hg. Understanding how elevation affects atmospheric pressure is important, as higher altitudes, like Denver, experience lower pressure due to the reduced weight of the air above.
