What would sunshine look like like if there were no sun?
If the barometer was any good it would read zero. Many barometers are not designed to handle that sort of extreme.

What can cause a vhange on air pressure?
One of the earliest forecasting tools was the use of atmospheric pressure. Soon, after the invention of the barometer, it was found that there were natural fluctuations in air pressure even if the barometer was kept at the same elevation. During times of stormy weather the barometric pressure would tend to be lower.
Does Barometric Pressure affect arthritic conditions?
A barometer is a tool used to measure atmospheric pressure. Storms are preceded by a drop in atmospheric pressure. This change can cause joints to swell due to the decrease in pressure on them. This can be painful, especially in arthritic joints.
Who discovered atmospheric pressure?
Evangelista Torricelli discovered atmospheric pressure. Secretly, he created an expierement with some of his friends. By filling a bowl with mercury and placing a six foot long glass tube upside down into it, a vacuum was created, causing the mercury to rise up. This was an early barometer. The reason this expierement was kept secret was probably because in 1643, this would have been considered witchcraft because a vacuum was considered impossible.
Does barometric pressure affect weight loss?
I would doubt it (you are talking about HUMAN weight loss, right? If not, don't bother reading this) because the pressure is pushing on us, and we are pushing back, so it really shouldn't change anything.
How to Predict the Weather Using a Barometer?
Of all weather instruments essential to forecasting, the barometer tops the list. Why? Because every weather change is preceded by a rise or fall in air pressure, and air pressure is just what the barometer measures. If you compare two barometer readings taken an hour or two apart, you will know immediately if the air pressure is rising, falling, or staying the same. And as a result you will be able, with a fair amount of accuracy, to predict tomorrow’s weather. RISING BAROMETER: When the air pressure measures higher than it did in your previous reading, the air is becoming denser, and the barometer is said to be rising. This tells you that clearer, drier, cooler weather is on the way. If the barometer is rising very rapidly from a low position, the weather will clear up very soon, and it will probably become quite windy. But if the barometer rises from a low position gradually and steadily, a long period of good weather is just around the corner. If the barometer is already high and suddenly starts to rise rapidly, expect a sudden drop to follow shortly, and with it, bad weather to come. FALLING BAROMETER: A falling barometer usually indicates rain, wind, and warmer weather. Take note of the speed at which the barometer falls. A very large and rapid drop in air pressure is a sure sign of an approaching storm. If the barometer falls suddenly, but not too far, expect wind and brief showers. If the barometer falls slowly and steadily to a moderately-low position, it may rain nearby, but not necessarily in your immediate area. UNCHANGING BAROMETRIC PRESSURE is a pretty good indication that whatever weather you’re currently enjoying is not about to change any time soon. IMPRESS YOUR FRIENDS AND NEIGHBORS! With a little experience in charting barometric pressure in your area, you will soon become skilled at noting any changes which are out of the ordinary. At this point, your weather-predicting abilities may begin to rival those of your local TV weatherman. And that would be something to brag about!

What was the Mercury barometer used for?
The mercury barometer is a tool used by meteorologists and other scientists to find the air, or "barometric" pressure. Because mercury is liquid at room temperature, it can change shape due to changes in the atmosphere. Earth's barometric pressure is characterized as the downward force of air on the surface of Earth. If mercury is placed in a tube and the level decreases by a huge increment, it would show an increase in barometric pressure. Mercury barometers can also be used to detect incoming storms as right before a storm, the air pressure decreases drastically.
What is a device that displays atmospheric pressure?
A barometer.Barometric pressure is usually read and rated in millibars of atmospheric pressure. A standard day at sea level, would be 29.9 on the barometric scale. That is, neither a high or low pressure in the area and generally sunny.
How does air pressure relate to air?
atmospheric pressure- and also temperature, decline with altitude. this is the principle behind all aneroid-based altimiters. The instrument, thus has to be compensated before flight by aligning with the current ground-level barometric pressure-all airports have weather stations and this information is passed to pilots by the control towers, hence Barometric pressure is Bracket Twenty nine-8. so the airmen would calibrate the barometer ( on the three o"clock position is a Kollsman window-to 29.8 which is the ground level barometric pressure- the Height indications would then read correct.The altimeter is a refined form of Aneroid barometer.
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.
Is barometric pressure the same as atmosheric pressure?
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.

Would it be hot or cold if a barometer was dropping?
A barometer does not measure temperature it measures pressure.
What instruments are used to measure the atmospheric pressure?
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
What would a baron do to a barometer?
He would use it to measure air pressure.
What is the surface pressure on your mother?
It would be the barometric pressure of the atmosphere which depends on the altitude of the person in question.
