Mountaineers often take oxygen tanks when they climb high mountains such as Everest. The tanks contain oxygen gas that has been compressed into small volume. This can help reduce the effect of atmospheric pressure

What happens to your body when atmospheric pressure changes?
When atmospheric pressure changes, your body can experience various physiological effects. A decrease in pressure, such as at high altitudes, can lead to reduced oxygen availability, causing symptoms like shortness of breath, dizziness, and fatigue. Conversely, an increase in pressure, like when diving underwater, can lead to increased gas absorption in your tissues, which can result in conditions like decompression sickness if not managed properly during ascent. The body often adjusts to these changes over time, but rapid shifts can pose health risks.
Is liquid petroleum gas a gas or a liquid?
Under normal temperature and atmospheric pressure conditions propane is gaseous. However, when the temperature is reduced to below −42.09 °C or when it is stored under high pressure (approx 177 psi), it takes the form of a liquid.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
What happens when volume changes?
Yes under constant pressure, with a given mass, volume changes during the change of state. When steam condenses, its volume is reduced. But, when water changes into ice, its volume becomes more. This is known to be anomalous expansion of water. Where as in other cases, when the liquid form gets changed into solid form, the volume is reduced.
If the pressure of a gas in a container is 10psi what will the pressure be in the volume of the container is reduced to one-half of its original size?
If the volume of the container is reduced to one-half of its original size, the pressure will increase proportionally according to Boyle's Law. So if the original pressure was 10 psi, then the new pressure would be 20 psi when the volume is reduced by half.
Why does the height of the liquid column in a barometer changes as atmospheric pressure changes?
Pressure tendancies measure short term weather. The mercury in a barometer will rise with atmospheric pressure denoting fairer weather and a fall in barometric pressure warns of inclement weather.

What effect doe altitude and air pressure have on each other?
As you go higher, air (atmospheric) pressure gets reduced.
Why Glycerin is distilled at reduced pressure?
glycerin is distilled at reduced pressure because it has boiling point of 290 degree celsius under atmospheric pressure it slightly decomposes but under reduced pressure it distills unchanged
How does atmospheric pressure affect the boiling point of matter?
Atmospheric pressure exerts pressure on the molecules of the liquid, confining them. In order to boil, the electrons must be excited, but must become hotter to overcome the pressure of the atmosphere. Therefore, pressure makes a liquid boil at a higher temperature. With a solid, the molecules are already compact together and have to be melted before they can be boiled. This does not require excitation of electrons, but it does require movement of electrons. Once the solid is melted, pressure will make it harder for the electrons to become excited.
How does air pressure help drinking through a straw?
when you drink through a straw you remove some of the air in the straw. Because there is less air pressure of the straw is reduced. But the atmospheric pressure on the surface of the liquid.
Does water boil faster at sea level than on the top of a mountain?
Water boils faster at sea level because there is higher atmospheric pressure, which increases the boiling point of water. At higher altitudes, such as on top of a mountain, the lower atmospheric pressure causes water to boil at a lower temperature, which means it takes longer to boil.
How does atmospheric pressure vary with elevation?
Atmospheric pressure decreases with increasing elevation due to the thinning of the air as altitude rises. At higher elevations, there is less air above to exert pressure, resulting in lower atmospheric pressure. This decrease in pressure is not linear; it drops more quickly at lower altitudes and gradually levels off at higher altitudes. As a result, climbers and those at high altitudes often experience reduced oxygen availability due to the lower pressure.
What is the atmospheric pressure on the top of Mt Whitney?
The atmospheric pressure on the top of Mt. Whitney, the highest peak in the contiguous United States, is about 30% lower than at sea level. This means the pressure is significantly reduced due to the higher altitude.
Why draft tubes are immersed in water?
to reduced the back flow of water because when water comes out from the runner the pressure is lower then the atmospheric pressure due to this back flow is generated.
Is liquid petroleum gas a gas or a liquid?
Under normal temperature and atmospheric pressure conditions propane is gaseous. However, when the temperature is reduced to below −42.09 °C or when it is stored under high pressure (approx 177 psi), it takes the form of a liquid.
The reduced vapor pressure at high altitudes causes a liquid to boil at a?
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point (i.e., the boiling point at atmospheric pressure) of the liquid.
