When air pressure increases the liquid in a mercury barometer would what?
The height of the Mercury column would decrease.
How do you find altitude pressure?
Pressure= Force/Area Pressure of a Liquid is density times gravity times height
How a barometer can be used to measure the vapor pressure of a liquid?
A mercury thermometer, that is a barometer can be used to measure vapor pressure. Initially, a proper temperature must be recorded. Then the liquid should be injected into the mercury column. This new measurement subtracted from the original will yield the vapor pressure of a liquid.
Why liquid rushes faster at the bottom hole than the tops?
liquid rushes faster at the bottom hole than tops because pressure in liquids is directly proportional to the height of the liquid.that is the deeper the liquid the higher the pressure
What is the difference between flash chromatography and column chromatography?
Column chromatography, is a broad term for all column chromatography methods, but is also synonomous with Gravity fed methods. Flash chromotography refers specifically to a column in which the eluant (or mobile phase) is moved through the column under pressure (using a hand pump for small scale, or a pressurised gas for a larger scale), the name Flash is derived from how much faster it is to run a column under pressure than via gravity.
Explain hydrostatic pressure?
Hydrostatic pressure is the pressure exerted by a liquid when it is at rest. It is directly proportional to the height of a liquid column of uniform density.
Why does the height of the column in a barometer changes as atmospheric pressure changes?
As the atmospheric pressure changes, the force pushing on the surface of the liquid changes. Therefore,the height of the liquid in the tube increases as the atmospheric pressure increases.
What is the relationship between liquid pressure and depth of a liquid?
As the depth of the fluid increases, the pressure increases. To explain this mathematicaly you consider the Sg of the fluid times the height of the column multiplied by gravity will give you the pressure at the base of the column
Why does the height of the liquid column in a barometer changes as atmospheric pressure changes?
Pressure tendancies measure short term weather. The mercury in a barometer will rise with atmospheric pressure denoting fairer weather and a fall in barometric pressure warns of inclement weather.
What would the pressure be in a liquid contained in a vertical tube sealed at the top with a submerged open bottom be?
It would be the same as the pressure in the liquid outside the tube at the open end- the deeper it is in the liquid, the higher the pressure.
Convert meter liquid column to bar?
The pressure of a liquid column of height h ("h meter liquid column) is: P = ρ*g*h [Bar], where ρ is the density of the liquid g is the gravitational acceleration (on Earth, in average 9.80665 m/s2)
Why do you think water from the different holes have different trajectories?
the trajectory of water is used as indicator of pressure. The longer the trajectory, the greater is the pressure at that point of the liquid column. Water pressure at any point in a closed container is dependent on the height of the liquid above it.
What will be happen if liquid other than water are used in variation of pressure with depth?
it depends on the vapour pressure of the liquid
What does mlc stand for pressure?
MLC stands for Mean Laplace Compliance, which is a metric used to evaluate pressure sensitivity in sensors. It measures how a sensor's output changes in response to pressure.
What turns from a liquid to gas?
Variation of pressure and temperature..that changes. Gas into liquid..temp should be decreased likewise pressure..
How can you change the volume of a liquid?
- by the variation of the temperature- by the variation of the pressure
What is the result from investigating liquid pressure at a particular level?
If the liquid is static or moving with a constant velocity, then liquid pressure at a particular level is constant.In case the liquid is in accelerated motion we will get variation in the liquid pressure at a particular level
