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.
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.
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.
Can you make a homemade barometer that works?
It will be difficult as the hose is opaque making reading it visually impossible.You will need roughly 30 feet of hose suspended vertically above the bucket with the top end sealed shut and filled with water.
What are the features of the stevenson screen?
Instruments which are used to measure temperature and Humidity should be kept inside "stevenson screen". Its a wooden box to shade from direct sunlight, Its painted white to reflect sunlight, It has vents to allow free flow of air. The stevenson screen should be located away from trees and buildings which could affect the temperature!

Why must of barometer be open to the air at one end and close to the other?
becuase my peepaw said so

Examples of a molecule in your body that can affect transcription factors?
A repressor, which works by binding to the operator and blocking the attachment of RNA polymerase to the promoter.

What factors affect the activity of enzymes?
Enzymes work best in the pH and temperature that they are " designed " for. A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH. Heat and out of range pH can denature enzymes and not only affect their activity but inactivate them.
How does the five factors affect the climate?
because the five factors are how the weather works, without clouds there would be no wind and so on, so without the factors there would be no weather and that is not possible
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.
Does alcohol affect Mirena?
Alcohol does not affect how well Mirena works.

Who uses a barometer?
Mainly meteorologists (weathermen), but chemists, engineers, and other scientists may. A barometer is an instrument used to measure pressure. Pilots and almost anyone involved with aviation use it. The altimeter in a plane works basically like a kind of barometer, and the barometric pressures affect the altimeter readings. It's very important to be able to correct for changing pressures, otherwise you could think you are at a higher altitude than you actually are, obviously dangerous.
