What is the barometer used for and how does it work?

A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.


Why is mercury used in barometers instead of water?

Because it has a high density... meaning that the volume increase or decrease due to altitude change is can be viewed in a practical sized barometer. If water, which had a much lower density, was used instead of mercury, the barometer must be at least 15m high.


Can you use a barometer below sea level?

Yes, a barometer can be used below sea level to measure atmospheric pressure. However, the reading may be slightly affected by the pressure of the water above it, which needs to be accounted for to obtain an accurate measurement.


Is used to measure the amount of the water vapor in the atmosphere?

The instrument used to measure the amount of water vapor in the atmosphere is called a hygrometer. It works by calculating the humidity levels in the air based on factors like temperature and the amount of water vapor present.


What are the different weather instrument?

How does an aneroid barometer measure atmospheric pressure?

A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury.An aneroid barometer is a barometer which measures pressure without using fluids!An aneroid barometer is somewhat different and uses a sealed chamber upon which the fluctuating atmospheric pressure acts. Through mechanical means a pointer is moved on a calibrated scale.


Can a barometer be used to measure the flow of water?

No, a barometer measures pressure.


What instrument measures pressure within a water system?

It's usually just called a "pressure gauge", the assumption being that you know, or a label on it tells you, that it is measuring water-pressure.


What deos a barometer measure?

A barometer is used to measure air pressure. It measures the atmospheric pressure using air, mercury, or water and will be shown as inches of mercury or millibars.

Why would a water barometer have to be 13.6 times taller than a mercury barometer?

A barometer using water,would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference. This is because mercury is 13.6 times more dense than water.

How is the can in the pan of water similar to the mercury barometer?

Both the can in the pan of water and the mercury barometer function based on the principle of atmospheric pressure. In both cases, changes in atmospheric pressure will cause a corresponding change in the level of water or mercury in the device. The height of the water or mercury serves as an indicator of the atmospheric pressure at that moment.


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 a bathymeter?

A bathymeter is another term for a bathometer - an instrument for measuring the depth of water.
