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

Verified step by step guidance

1. Identify the conversion factor from torr to pascals. The conversion factor is 1 torr = 133.322 pascals.
2. Write down the given pressure in torr, which is 823.7 torr.
3. Set up the conversion equation using the conversion factor. Multiply the given pressure by the conversion factor to convert the pressure from torr to pascals.
4. Perform the multiplication to find the pressure in pascals.
5. Express the final answer in pascals with appropriate significant figures based on the given data.

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, millimeters of mercury (mmHg), and pascals (Pa). Understanding barometric pressure is essential for meteorology and various scientific applications, as it influences weather patterns and altitude measurements.

Unit Conversion

Unit conversion is the process of converting a quantity expressed in one set of units to another. In this case, converting torr to pascals requires knowing the relationship between these units: 1 torr is equivalent to approximately 133.322 pascals. 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 can be expressed in various units, including pascals (Pa), atmospheres (atm), and torr. Each unit serves specific contexts; for example, pascals are the SI unit of pressure, while torr is often used in meteorology and vacuum measurements. Familiarity with these units is vital for interpreting and communicating scientific data.
