How would the reading of a barometer change as you decrease in altitude?
As you decrease in altitude, the reading of a barometer will increase. This is because atmospheric pressure is higher at lower elevations due to the greater weight of the air above. Consequently, a barometer measures this increased pressure, resulting in a higher reading as you descend.
Why would a barometer show a greater reading when taken into a coal mine?
A barometer shows a greater reading when taken into a coal mine because the air pressure is higher underground due to the weight of the earth's atmosphere above it. This increased pressure causes the barometer to indicate a higher reading.
Why does a barometer have a higher reading at sea level then at the top of the mountain?
Air pressure on earth results from the earth's gravitational pull on the earth's atmosphere. In some sense, pressure results from the weight of the air above the point at which one measures pressure. At higher altitudes, there is less air above, resulting in less weight, which translates into pressure.
What happens if you bring a barometer down a mine?
As you bring a barometer down a mine, the atmospheric pressure increases because of the weight of the air above pushing down. This causes the barometer to indicate a higher pressure reading compared to the surface. This increase in pressure can be used to estimate the depth of the mine shaft.
You carry a barometer with you to the top of a very tall buildingyou notice that the barometer reading goes down as you ride up to the107th floorexplain what happened and why?
Barometer's measure air pressure and the Earth's air pressure at a certain place is due to the weight of the air above it. So the higher you go the air pressure drops because there is less air above you pushing down with its weight.
Can you use a barometer below sea level?
Yes, a barometer can be used below sea level to measure atmospheric pressure. However, the reading may be slightly affected by the pressure of the water above it, which needs to be accounted for to obtain an accurate measurement.
What changes in air pressure what would you expect if you carried a barometer down a mine shaft?
Density and air pressure will increase, while altitude decreases.
What accounts for the difference in heights of mercury vs water columns?
Density
What would you use to measure the elevation above sea level on air temperature and air pressure?
elevation above sea level . . . barometer or GPS air temperature . . . thermometer air pressure . . . barometer
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.
What are the uses of mercury barometers?
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.Read more: Uses_of_mercury_barometer
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.
