What changes in air pressure would you expect if you carried barometer down a mineshaft?
As you descend down a mineshaft, the air pressure would increase due to the weight of the air above you pressing down. This is because air pressure is directly proportional to the density of the air above a given point. The barometer would register a higher pressure reading as you go deeper into the mineshaft. Conversely, as you ascend back to the surface, the air pressure would decrease, resulting in a lower pressure reading on the barometer.

Can a barometer be used as an altimeter?
With a little modification yes. The principals of design for the Barometer and Altimeter are the same. A sealed capsule expands and contracts with changes in air pressure, this movement is then changed to the movement of a dial to get a scaled reading. However the Barometer would need its scale changing to read in terms of altitude. This would allow a rudimentary calculation of altitude, however as the air pressure changes, the altitude read on the scale would change. The Altimeter as used in aircraft also has a small thumb wheel or turntable knob that allows you to set the air pressure to the air pressure of the ground. This makes the scale more accurate, and negates any changes in air pressure.
Matter changes state because of?
Matter changes state because of temperature and pressure. These quantities bring change.
A blown up balloon is carried up a high mountain will it get bigger or smaller explain why its volume changes?
As balloons increase in altitude, there is less atmospheric pressure pushing on it, so the result is that the balloon expands. The opposite is true, if you sink a balloon in water there is more pressure on the outside of the balloon so it shrinks.
Gases do not have definite?
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.
What is the laboratory air pressure in ATM?
The air pressure changes based on altitude, but at sea level, it is 1 atm, or 760mmHg, or 760Torr.
What changes in air pressure would you expect if you carried a barometer a mine shaft?
Density and air pressure will increase, while altitude decreases.
What changes in air pressure you expect if you carried a barometer down a mine shaft?
Density and air pressure will increase, while altitude decreases.
A barometer is an instrument used for measuring water pressure?
otherwise know as a barometer and it measures air pressure in newtons
Is air pressure measured with a barometer?
Yes, air pressure is typically measured with a barometer. A barometer is a device that detects changes in atmospheric pressure and provides a numerical value to represent the pressure.
How you can use the word barometer in a sentence?
i checked the barometer to see the air pressure
What does rapid changes in the barometer mean?
Rapid changes in the barometer typically indicate rapidly changing weather conditions. A falling barometer suggests approaching low pressure and typically signifies stormy weather, while a rising barometer indicates high pressure and often signifies fair weather. Monitoring barometer trends can help anticipate weather changes.
What dobarometers measure?
A barometer - measures changes in atmospheric pressure.
What is the tool that records air pressure changes?
Barometer is the instrument that measures air pressure
What kind of barometer measures air pressure by using a metal chamber that is sensitive to pressure changes?
The kind of barometer you are referring to is a aneroid barometer. It uses a metal chamber (an aneroid cell) which expands or contracts with changes in air pressure. This movement is then converted into a reading of air pressure on a dial.
Why does Mercury stay in the barometer?
A barometer is a closed-system vacuum that allows the mercury to expand with changes in temperature and pressure.
How can you use a barometer to detect changes in air pressure?
A barometer is used in 2 ways. First you keep it stationary. You record the pressure. If the pressure drops, it means, a storm is coming. Second, in a car or airplane when the barometer falls, it means you are getting higher. When the barometer drops, it means you are getting lower.
What is a mercury barometer used for?
Mercury barometer is used for measuring atmospheric pressure. Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.
