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.
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.
Does the speed of sound change with altitude?
Yes, the speed of sound does change with altitude. In general, the speed of sound increases with higher altitudes due to the decrease in air density.
Why does air pressure change with altitude?
Air pressure changes with altitude because as you go higher in the atmosphere, there is less air above pushing down on you. This results in lower air pressure at higher altitudes.
Air at lower altitude is what compared to air at higher altitude?
the higher you are the more the density decreases
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.
How would the reading on a barometer change if you were to take one on a trip from Los Angeles to Lake Tahoe which is at a much higher altitude?
As you travel from Los Angeles to Lake Tahoe, the reading on the barometer would decrease. This is because barometers measure atmospheric pressure, which decreases with increasing altitude. At higher elevations, like Lake Tahoe, the air is less dense, resulting in lower pressure readings compared to sea level in Los Angeles. Thus, you would observe a drop in the barometric pressure as you ascend to the higher altitude.
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.
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.
What happens to an aneriod barometer when air pressure changes?
When air pressure increases, the aneroid barometer contracts, causing the needle to move clockwise or indicate a higher pressure reading. Conversely, when air pressure decreases, the aneroid barometer expands, causing the needle to move counterclockwise or indicate a lower pressure reading.
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.
Is it possible to have a higher barometer reading at 1000 ft above sea level then you do at sea level?
When you have the same weather (high or low pressure region) then 1000 ft higher on top of a hill you will have lower barameter reading. On the hill there is not so much air over you. That's why there must be less pressure on you and on the barometer.
Is it safe to take an aneroid barometer on an airplane?
Commercial aircraft are pressurized to the equivalent of 8,000 ft of altitude, or lower. That means air pressure in the cabin is lower, not higher. Many people in Colorado live at 8,000 ft. Your barometer should be fine.However, while you could bring a dial type barometer aboard the aircraft, a mercury barometer could not be (hazard of the mercury in it.)
Are height and altitude the same?
Almost. Altitude pretty much sounds as if it [only] originates from the readings as provided by an Altimeter - and this is based upon the Barometer which is in turn based upon the measurement of Atmospheric Pressure [Higher Altitude means Lower Pressure]. Height will continue to increase as you rise in elevation. Altitude will do the same only as long as there is an Atmosphere present.
What reading would a barometer give in Madison'Wisconsin?
A barometer measures atmospheric pressure, and its reading in Madison, Wisconsin, would typically be around 29.92 inches of mercury (inHg) at sea level under standard conditions. However, this value can fluctuate based on weather patterns, with lower readings indicating stormy weather and higher readings suggesting fair conditions. For an accurate current reading, a local weather service or a personal barometer would need to be consulted.
Does the speed of sound change with altitude?
Yes, the speed of sound does change with altitude. In general, the speed of sound increases with higher altitudes due to the decrease in air density.
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.
