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.
What would a baron do with a barometer?
The same as anyone else. Use it to find out the atmospheric pressure
How does the pressure at the bottom of a 76-cm column of mercury in a barometer compare with the air pressure at the bottom of the atmosphere?
If the barometer is in the same place where you're measuring the air pressure, then they're exactly equal.
Is a Fujita scale the same as a barometer?
No, the Fujita scale rates tornadoes from F0 to F5 based on the severity of their damage. It is a system, of assessing tornadoes, not an actual measurement device. A barometer is an instrument that measures air pressure.
How do you adjust barometer for altitude?
Here is what I did for my barometer. I looked up the local barometric pressure online. Then I turned the altitude adjuster on the barometer until the reading was the same as the reading that I looked up online. If I am at roughly the same altitude as the one taken online, then I know that the altitude has been adjusted correctly when both barometers have the same reading. It is a backward method of doing it, but it should work. This should be close enough for casual use. If you want to actually collect scientific data, you might need a better method.
How does the pressure at the bottom of a 76 cm column of mercury in a barometer compare with air pressure at the bottom of the atmosphere?
The pressure at the bottom of a 76 cm column of mercury in a barometer would be equal to the atmospheric pressure pushing down on the mercury column. This is because the height of the mercury column in a barometer is directly related to the atmospheric pressure. Thus, the pressure at the bottom of the mercury column would be the same as the air pressure at the bottom of the atmosphere.
Is barometric pressure the same as air pressure?
Yes, barometric pressure is a specific type of air pressure that is measured using a barometer.
If tomorrow is today what was yesterday?
The answer is today. The answer is always today, it was the same yesterday and it will be the same tomorrow.
Describe how a mercury barometer measure air pressure?
The basic principle of barometer is Torricelli's experiment. Imagine that you fill a tube of one metre length (100cm) with mercury up to the brim. Then close the mouth of the tube with your thumb and invert the tube and place it in a cistern of mercury with its end immersed in the mercury say some 4 cm. Now you remove your thumb. Mercury would come down but it stops at one level to our astonishment. This level would be some 20 cm from the closed end of the tube. So there will be almost 76cm column of mercury in the tube. Why is it so? As mercury comes down the space left vacant will not be having any air molecule and so it is almost vacuum. This is named as Torricelli's vacuum. Now the air outside in the atmosphere would exert a pressure and wants to push the mercury towards this vacuum place. But the weight of the mercury column (76cm) will balance this pressure. Hence we say the atmospheric pressure will be 76 cm of mercury. This is how we have mercury scale for measuring the pressure. Usually pressure is defined as the force per unit area. Hence the unit will be N/m2 or pascal. But we give pressure only in cm or mm of mercury. The reason is explained properly. Same technique is applied in Fortin's barometer and vernier arrangement is made to measure the pressure so accurately.
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.
Witch political party was in 1998?
Democratic and Republican
Who is the inventor of hydrometer?
Possibly one of the Italian scientists of the period of Torricelli and Galileo who were involved with Weather instruments such as the now-obsolete columnar barometer still used metaphorically in fund raising events! The clever argument that Wassermann ( of VD blood test fame) invented the Hydrometer appears to be play on words ( Wassermann literally means Water Man) -but they do use the same scale- 4.l0 being the highest reading ( applies to battery hydrometers of the more modern type- and the Syphilis test. oh by the way it is 4.0 or 4 Plus.
