How does a barometer measure humidity?
It doesn't, it measures atmospheric pressure. Humidity is measured with a hygrometer.* Some long case mercurial barometers, used in the home, may have a separate hygrometer included on the instrument.
How do fortin barometers work?
The way the Fortin barometer works is different in a sense that it uses atmospheric pressure to balance the weight of a column of mercury against it. From that, any change in the atmospheric pressure is accompanied by an immediate change in the level of the mercury and can be measured against the scale engraved on the barometer.
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.
What are the difference between the mercury barometer and aneroid barometer?
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
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.
An apparatus used for measuring the atmospheric pressure?
A barometer is the apparatus used for measuring atmospheric pressure. It works by balancing the weight of the atmosphere against a column of mercury or other fluid, which in turn reflects the pressure of the air above it.

Why must of barometer be open to the air at one end and close to the other?
becuase my peepaw said so
What is the name of barometer which does not contain liquid?
It's known as an aneroid barometer. It works by the difference in pressure causing a partially flattened tube which is wound into a coil to straighten out. The movement is converted to circular motion by a series of gears. the central shaft has a needle attached which indicates the pressure.
What does a mercury barometer measure and how does it work?
A mercury barometer measures atmospheric pressure, which is the weight of the air pressing down on Earth's surface. It works by using a column of mercury in a sealed tube to balance the pressure of the air outside. When the air pressure increases, the mercury in the tube rises, and when the air pressure decreases, the mercury falls.
What is the principle of barometer?
A barometer works on the principle that atmospheric pressure changes with weather conditions. By measuring this pressure, a barometer can indicate whether the pressure is rising (indicating good weather) or falling (indicating poor weather). This allows for forecasting changes in the weather.

What was the device that Torricelli invented for measuring air pressure called?
The device that Torricelli invented for measuring air pressure is called a barometer. It works by balancing the weight of the atmosphere with the weight of a column of mercury in a glass tube.
