When climbing a mountain with a barometer will the mercury level decrease or increase?
As you climb a mountain, the atmospheric pressure decreases with altitude, causing the mercury level in the barometer to decrease. This is because there is less air pressing down on the mercury in the barometer as you ascend, leading to a lower reading.
Where is air density is greatest?
At the bottom of the troposphere
What is the partial pressure of oxygen on Mt Everest if the atmospheric pressure on Mt Everest is one-third the atmospheric pressure at sea level?
The partial pressure of oxygen on Mt Everest would be approximately one-third of the partial pressure of oxygen at sea level, assuming a constant composition of air. This decrease is due to the decrease in atmospheric pressure at higher elevations. This lower partial pressure of oxygen can lead to decreased oxygen availability for breathing at high altitudes.
Is there high or low pressure on top of mountains?
There is lower air pressure on top of mountains compared to sea level, due to the decrease in atmospheric density as altitude increases.
How would the altitude and the atmospheric pressure of Johannesburg affect the boiling point of water?
The higher altitude in Johannesburg will result in lower atmospheric pressure. Lower pressure causes water to boil at a lower temperature than at sea level. This means water will boil at a lower temperature in Johannesburg compared to sea level locations.
Does the atmospheric pressure increase or decrease as you move upward away from sea level?
Atmospheric pressure decreases as you move upward away from sea level due to the decrease in the weight of the air above pushing down. This means that atmospheric pressure is lower at high altitudes and higher at lower altitudes, such as at sea level.
As you walk down a mountainside atmospheric pressure will what?
It will increase. Atmospheric pressure decreases with altitude and increases as you move toward sea level. At sea level, atmospheric pressure = 1.0
Why does atmospheric pressure start to decrease around midnight when with the temperature decrease pressure should increase?
The reason for temperature being lower in high altitude regions (as compared to places at sea-level) is due to the decrease in atmospheric pressure as we go up in altitude. So decrease in atmospheric pressure causes the temperature to decrease, which might be a reason for the decreased pressure at night. --- Diurnal temperature fluctuations vary by location, but follow a twice-daily cycle of general rise and fall, corresponding to the "atmospheric tide" induced by the eastward rotation of the planet.
When climbing a mountain with a barometer will the mercury level decrease or increase?
As you climb a mountain, the atmospheric pressure decreases with altitude, causing the mercury level in the barometer to decrease. This is because there is less air pressing down on the mercury in the barometer as you ascend, leading to a lower reading.
What is the pressure above sea level in mmHg?
The atmospheric pressure at sea level is typically around 760 mmHg. As you increase in altitude above sea level, the atmospheric pressure decreases. For example, at 5,000 feet above sea level, the atmospheric pressure may be around 625 mmHg.
What happens to the atmospheric pressure as one rises from sea level to the therosphere?
Rising from the sea level to the higher levels will result in decrease of temperature and pressure.
Where is air density is greatest?
At the bottom of the troposphere

The partial pressure of oxygen on Mt Everest would be approximately one-third of the partial pressure of oxygen at sea level, assuming a constant composition of air. This decrease is due to the decrease in atmospheric pressure at higher elevations. This lower partial pressure of oxygen can lead to decreased oxygen availability for breathing at high altitudes.
How does the atmospheric pressure at altitudes sea level compare with atmospheric pressure at sea level?
the atmospheric pressure below sea level is highter (novanet)
How does the atmospheric pressure below sea level compare with atmospheric pressure at sea level?
It is greater.
What is the atmospheric pressure at sea level in pascal?
The atmospheric pressure at sea level is approximately 101,325 pascals.
What is the atmospheric pressure at the bottom of the Grand Canyon?
The atmospheric pressure at the bottom of the Grand Canyon is approximately 90 kPa (kilopascals), which is slightly lower than the standard atmospheric pressure at sea level (about 101.3 kPa). This decrease in pressure is primarily due to the elevation of the Grand Canyon, which is about 1,200 meters (around 4,000 feet) above sea level. As altitude increases, the atmospheric pressure decreases, resulting in the lower pressure observed at the canyon's depth.
