In this lesson, we will learn how to describe the mechanisms of common gas pressure gauges and how to identify sources of error in pressure measurements.
A manometer is used to measure the pressure of a gas; the gas exerts a force on a column of liquid in the u-tube, causing it to fall at one end and rise at the other. Which of the following properties would make a liquid a bad choice for use in a manometer?
How would the use of a volatile liquid affect the measurement of a gas using open-ended manometers versus closed-end manometers?
