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

Verified step by step guidance

1. Identify the conversion factor between torr and bars. The conversion factor is that 1 bar equals 750 torr.
2. Set up the conversion equation using the given pressure in torr and the conversion factor. This can be expressed as: \( \text{Pressure in bars} = \frac{\text{Pressure in torr}}{750 \text{ torr/bar}} \).
3. Substitute the given pressure value into the equation: \( \text{Pressure in bars} = \frac{823.7 \text{ torr}}{750 \text{ torr/bar}} \).
4. Perform the division to convert the pressure from torr to bars.
5. Ensure the final answer is expressed in bars 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, pascals, or bars. 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 bars requires knowledge of the relationship between these units. Specifically, 1 bar is equivalent to 750.062 torr, which is crucial for accurate pressure calculations.

Pressure Units

Pressure is a measure of force applied per unit area and can be expressed in various units, including torr, bars, and pascals. Each unit has its own context of use; for example, bars are often used in meteorology and engineering. Familiarity with these units and their conversions is vital for solving problems related to pressure.
