In principle many different liquids could be used in a barometer. Mercury is usually preferred by virtue of its low vapour pressure and high density. As part of a school project, you have decided to build a barometer using water. Assuming the maximum pressure that the instrument will need to read is 1.05 atm, determine the height of the column required if (a) you ignore the vapour pressure of water or (b) you take the vapour pressure of water (PH2O=3.17...

EXPERIMENT 12 Name MEASUREMENT OF THE GAS CONSTANT PRE-LAB EXERCISES Central to the study of gases is the idea of pressure. Historically pressure was determined as the ability the raise a column of mercury (Hg) to a particular height. Today, pressures are still often (erroneously) quoted just as a simple distance measurement, such as 75 cm. What is really meant is a column of Hg 75 cm high, so it is not too bad to say P - 75 cm...

please help! this is a fluids question in physics.
1-3 (a) What is the height of a fluid column in a barometer that uses water as its 5 pts fluid in 0.924 atm of air pressure? The density of water is 1000 kg/m'. Neglect the vapor pressure in the apparently empty space above the column. Use g = 9.80 m/s² and give the height in meters. m( + 0.02 m) (b) What is the height if the fluid is mercury?...

Part B Review Constants Periodic Table Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average...
