The highest barometric pressure ever recorded was 823.7 torr at Agata in Siberia, Russia on December 31, 1968. Convert this pressure to (e) psi.

Verified step by step guidance

1. Identify the given pressure in torr: 823.7 torr.
2. Recall the conversion factor between torr and psi: 1 atm = 760 torr and 1 atm = 14.696 psi.
3. Convert the pressure from torr to atm using the conversion factor: \( \text{Pressure in atm} = \frac{823.7 \text{ torr}}{760 \text{ torr/atm}} \).
4. Convert the pressure from atm to psi using the conversion factor: \( \text{Pressure in psi} = \text{Pressure in atm} \times 14.696 \text{ psi/atm} \).
5. Perform the calculations to find the pressure in psi.

Key Concepts

Barometric Pressure

Barometric pressure is the pressure exerted by the weight of the atmosphere at a given point. It is commonly measured in units such as torr, pascals, or atmospheres. Understanding barometric pressure is essential for various applications, including weather forecasting and studying atmospheric phenomena.

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 pressure from torr to psi (pounds per square inch) requires using a conversion factor. Mastery of unit conversion is crucial in chemistry and physics to ensure accurate calculations and comparisons.

Pressure Units

Pressure is a measure of force applied per unit area, and it can be expressed in various units, including torr, psi, and pascals. Each unit has its own context and application; for example, psi is commonly used in engineering and automotive contexts. Understanding these units and their relationships is vital for interpreting and communicating scientific data.
