Can humidity effect the reading of a barometer?
No , a Barometer measures air pressure.
What is the use of barometer in detail?
barometer is an instrument used to measure the pressure in the atmosphere and it also gives as an accurate reading.
What instrument must you tap before reading it?
One traditionally taps a barometer before taking the pressure reading and weather forecast.
Why does a barometer fall before it rains?
Air pressure is the weight of the air around us. When there is a period of low pressure, a barometer detects this and displays it with the needle. This reading is showing the weight of the air. It normally rains during a period of low pressure, so if the needle on the barometer is pointing to low pressure or rain, you can predict what the weather will be like in the following days. Hope this answers your question.
What predictions about the weather can be made as the barometer reading falls?
if the barometer reading falls it means bad weather is coming

When the barometer reading goes upwe have a pressure area?
air pressure
What is the use of barometer in detail?

What is an example sentence for the word barometer?
The barometer shows low air pressure in a hurricane.My pain increases when the barometer drops below 29.8 to 30.A barometer gives a reading of air pressure.
What is a barometers?
A barometer is a device used to measure atmospheric pressure. If pressure is high (good weather), then pressure on the barometer will exceed 1000 millibars. If the pressure is low (bad weather), then the pressure reading on the barometer will be below 1000 millibars.
What does low pressure reading in a barometer mean?
Generally it means it is going to rain.
What is the function of barometer?
The function of a barometer is to measure atmospheric pressure. This reading aids in making short-term weather predictions like high-pressure ridges and frontal boundaries.
What You Get From aneriod barometer?
A reading of the air pressure. It's handy for rough weather predictions.
What instrument must you tap before reading it?
One traditionally taps a barometer before taking the pressure reading and weather forecast.
How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?
Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.
What instrument must you tap before reading the barometer on it?
do you have to tap a barometer daily to get correct reading
What is air pressure at Denver Colorado?
Air pressure is measured in different ways. Two common ones are PSI (pounds per square inch) or a barometer which measures in column inches of mercury. As we know the barometer goes up and down with weather so the air pressure goes up and down. The highest barometer reading ever recorded is about 32 inches or just over 15.6 PSI. The lowest barometer reading ever recorded was 25.69 in the middle of a hurricane so this is not typical but equates to about 12.5 PSI. These are all sea level readings. So we need an average, or normal. The standard is a barometer of 29.92 which equates to about 14.7 PSI, again being a sea level reading. With that standard the pressure at Denver is 12.1 PSI or a barometer of about 24.63. At this pressure water boils at about 202F instead of 212F.
