On a climb up Mount Whitney, the atmospheric pressure dropsto 467 mmHg. What is the pressure in terms of the following units?b. torr

Verified step by step guidance

1. Understand that the unit 'torr' is equivalent to 'mmHg'.
2. Recognize that 1 torr = 1 mmHg.
3. Since the atmospheric pressure is given as 467 mmHg, it is directly equivalent to 467 torr.
4. No conversion is necessary because the units are the same.
5. State that the pressure in torr is the same numerical value as in mmHg, which is 467 torr.

Key Concepts

Atmospheric Pressure

Atmospheric pressure is the force exerted by the weight of air above a given point, typically measured in units such as mmHg, torr, or atmospheres. At sea level, standard atmospheric pressure is approximately 760 mmHg. As altitude increases, such as on a mountain, atmospheric pressure decreases due to the reduced weight of the air above.

Unit Conversion

Unit conversion is the process of converting a measurement from one unit to another while maintaining the same quantity. In this case, converting mmHg to torr is straightforward since 1 mmHg is equivalent to 1 torr. Understanding how to perform these conversions is essential for accurately interpreting and comparing pressure measurements.

Torr

The torr is a unit of pressure defined as 1/760 of an atmosphere, which is equivalent to 1 mmHg. It is commonly used in various scientific fields, particularly in chemistry and physics, to express low pressures. Knowing that 1 torr equals 1 mmHg allows for easy conversion between these two units when analyzing pressure data.
