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
As you go higher, air (atmospheric) pressure gets reduced.
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
PRESSURE (atmospheric) effects the sinus membraneSEE what a plumber has to know
The atmospheric pressure has no effect on the speed of sound when the temperature is constant. The air pressure has no influence on the sound.
The height of the liquid column in a barometer changes as atmospheric pressure changes because atmospheric pressure exerts force on the liquid in the barometer tube. As atmospheric pressure increases, it pushes the liquid column higher to maintain balance. Conversely, as atmospheric pressure decreases, the liquid column falls due to reduced pressure pushing up from below.
Atmospheric pressure
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.
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.
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.
Total pressure is equal to the sum of gauge pressure and atmospheric pressure. Atmospheric pressure is always present and contributes to the total pressure measurement.
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.
