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.
Could a mercury barometer be used to measure the barometric pressure of the atmosphere on mars?
No, a mercury barometer relies on the density and height of a column of mercury in a tube to measure atmospheric pressure. However, Mars has a thin atmosphere with low pressure, so mercury would not provide accurate readings. Other pressure-measuring devices, like electronic sensors, would be more suitable for measuring barometric pressure on Mars.
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.
How would a barometer reading change with a cold front?
A barometer reading would change with a cold front because the density of mercury will change with temperature, so a reading must be adjusted for the temperature of the instrument. For this purpose a mercury thermometer is usually mounted on the instrument. Temperature compensation of an aneroid barometer is accomplished by including a bi-metal element in the mechanical linkages. Aneroid barometers sold for domestic use typically have no compensation.

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.

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.
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 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.
If Torricelli had drilled a little hole at the top of his barometer?
If Torricelli had drilled a little hole at the top of his barometer, the mercury inside would not have remained in a vacuum at the top. Instead, air would enter the tube, equalizing the pressure and causing the mercury to drop, rendering the barometer ineffective for measuring atmospheric pressure changes. This illustrates the importance of maintaining a sealed environment in barometric measurements to ensure accurate readings.
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.
