The height of the Mercury column would decrease.
What else can I help you with?
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.
Does a mercury barometer or aneroid barometer measure air pressure?
mercury has a sudden fall and then the barometter measure it and when i mean by fall i mean air pressure so yeah it's cool I knoe it doesn't make sense but Im just writing this anyway. Even though it's pure glorius silly you know what. I PUT THAT WORD BUT THEY WON'T LET ME POST THIS STUPID ANSWER
What are the parts of a Barometer?
A barometer consists of a glass tube filled with mercury or water, sealed at one end and open at the other. The open end is submerged in a dish of mercury or water to measure air pressure. The height of the liquid in the tube changes with changes in atmospheric pressure.
What is an instrument that measures changes in air pressure using liquid mercury?
Any liquid can actually be use in a tube (barometer) to measure air pressure, but there are various advantages in using mercury for the purpose. 1. Mercury is a shiny liquid (a liquid metal) so it can be easily seen through the glass tube. Other liquid like water are transparent. 2. Mercury is very heavy. So only 76cms of it rises in the tube. Had you been using water for the purpose, you would need a glass tube as long as 55ft. 3. Mercury does not stick to the glass surface inside, so the reading obtained is much more accurate and precise. Remember: Water droplets stick to glass.
What is an aneroid barometer called?
Well, an aneroid barometer, is called an aneroid barometer- but, a barometer measures air pressure, and an aneroid barometer is a barometer that contains no liquid.
When air pressure goes up the liquid in a mercury barometer goes?
When air pressure goes up, the liquid in a mercury barometer goes down. This is because as air pressure increases, it pushes the mercury in the tube to rise, indicating higher pressure.
What is in a thermometer and a barometer?
A thermometer measures temperature - most are now electric but they used to have alcohol or mercury in them. A barometer measures air pressure - they are now electric but used to have air in them (in a bellows with a spring).

What kind of liquid is found in a barometer?
Mercury is the liquid typically found in a barometer. It is used to measure atmospheric pressure due to its density and ability to rise and fall within the tube as pressure changes.
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.
When you measure air pressure most accurately you should use a mercury?
barometer. Mercury barometers are very accurate instruments for measuring air pressure because the height of the mercury column is directly proportional to atmospheric pressure. Mercury is a dense liquid, making slight changes in pressure more visible in the barometer.
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.
Types of Barometers?
The two common types of barometers are mercury barometers, which use the height of mercury in a column to measure atmospheric pressure, and aneroid barometers, which utilize a flexible metal membrane to detect and measure pressure changes without using liquid. Digital barometers are also becoming more popular, using electronic sensors to measure pressure.

What liquid metal is found inside of a barometer?
Mercury.

Structure of barometer?
A barometer typically consists of a glass tube filled with mercury or a liquid metal, sealed at one end and open at the other. The open end is placed in a container of mercury, allowing atmospheric pressure to push the mercury up the tube. The height of the mercury column is a measure of the atmospheric pressure.
