Capitolo 10, Problema 21
In the United States, barometric pressures are generally reported in inches of mercury (in. Hg). On a beautiful summer day in Chicago, the barometric pressure is 30.45 in. Hg. (a) Convert this pressure to torr.
Guida verificata passo dopo passo1
Step 1: Understand the relationship between inches of mercury and torr. 1 inch of mercury (in. Hg) is equivalent to 25.4 torr.
Step 2: Identify the given pressure in inches of mercury, which is 30.45 in. Hg.
Step 3: Set up the conversion by multiplying the given pressure in inches of mercury by the conversion factor (25.4 torr/in. Hg).
Step 4: Perform the multiplication: 30.45 in. Hg * 25.4 torr/in. Hg.
Step 5: The result of this multiplication will give you the pressure in torr.
Concetti chiave
Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Barometric Pressure
Barometric pressure is the pressure exerted by the weight of the atmosphere at a given point. It is commonly measured using a barometer and is expressed in various units, including inches of mercury (in. Hg) and torr. Understanding barometric pressure is essential for meteorology and various scientific applications, as it influences weather patterns and altitude measurements.

Pressure Units
Unit Conversion
Unit conversion is the process of converting a quantity expressed in one set of units to another set of units. In this case, converting inches of mercury to torr involves using a specific conversion factor, where 1 in. Hg is equivalent to 25.4 torr. Mastery of unit conversion is crucial in chemistry and physics to ensure accurate calculations and comparisons across different measurement systems.

Torr
The torr is a unit of pressure defined as 1/760 of standard atmospheric pressure, which is equivalent to the pressure exerted by a 1 mm column of mercury at 0°C. It is commonly used in scientific contexts, particularly in vacuum measurements and gas laws. Understanding the torr is important for interpreting pressure readings in various scientific fields, including chemistry and physics.
