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-end manometers versus closed-end manometers?
The pressure of a sample of gas is measured with a closed-end manometer containing liquid mercury, as shown in the figure. The density of mercury is 13.6 g/mL and the acceleration due to gravity is 9.81 m/s2. What is the pressure of the gas sample?
