In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level
(see the related links for charts)
However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country

What else can I help you with?
What would be the boiling point of alcohol at a higher altitude?
The boiling point of alcohol decreases at higher altitudes due to the lower atmospheric pressure. As altitude increases, atmospheric pressure decreases, causing liquids to boil at lower temperatures. This means that alcohol will boil at a lower temperature at higher altitudes compared to sea level.
What is the relationship of oxygen density to altitude?
Oxygen density decreases as altitude increases. This is due to the decrease in atmospheric pressure at higher altitudes, which results in a lower concentration of oxygen molecules. Therefore, the higher the altitude, the lower the oxygen density.
Why is the boiling point in Durban different from that in Johannesburg?
Boiling point is dependent on air pressure. Air pressure is dependent on altitude. Durban is coastal, almost sea level. Johannesburg is inland, quite a bit higher. High altitude = low air pressure = low boiling point.
Why does the boiling temperature of water decrease when the water is under reduced pressure such as it is in a higher altitude?
At higher altitudes, there is reduced atmospheric pressure, which leads to a lower boiling point of water. This happens because with lower pressure, it is easier for water molecules to escape into the air as vapor. Therefore, at higher altitudes, water reaches its vapor pressure (boiling point) at a lower temperature than at sea level.
Does melting point change from altitude to altitude?
Yes, the melting point of a substance can change with altitude due to the variation in atmospheric pressure. As altitude increases, atmospheric pressure decreases, which can affect the boiling and melting points of substances. Generally, lower pressure at higher altitudes can result in lower melting points for many substances.
Air at lower altitude is what compared to air at higher altitude?
the higher you are the more the density decreases
What is the relation between the altitude compared to sea level and the boiling point of water?
In general, the higher the altitude, the lower the pressure, and the lower the pressure the lower the boiling point.
What can be done to raise the boiling point of water?
All you have to do to reduce the boiling point of water is go to a higher altitude and boil it.
True or false the higher the altitude the lower the air pressure?
true?
How does air pressure vary with altitude?
Air pressure decreases with increasing altitude. This means that as you go higher in the atmosphere, the air pressure becomes lower.
Why does pressure decrease with altitude?
Pressure decreases with altitude because as you go higher in the atmosphere, there are fewer air molecules above you exerting pressure downwards. This results in lower atmospheric pressure at higher altitudes.
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.
What does air pressure do when altitude increases?
Air pressure decreases with increase of height.
Is the vapor pressure of water lower at higher altitude?
Yes, the vapor pressure of water is lower at higher altitudes due to the reduced atmospheric pressure. As altitude increases, the fewer molecules in the air exert less pressure on the water's surface, causing it to evaporate more slowly.
What happen to the air pressure in a higher altitude?
Air pressure decreases at higher altitudes because there is less air above pushing down on the atmosphere. This decrease in pressure can lead to lower oxygen levels, making it more challenging to breathe at higher elevations.
What would be the boiling point of alcohol at a higher altitude?
The boiling point of alcohol decreases at higher altitudes due to the lower atmospheric pressure. As altitude increases, atmospheric pressure decreases, causing liquids to boil at lower temperatures. This means that alcohol will boil at a lower temperature at higher altitudes compared to sea level.
What will happen to the atmospheric pressure as the altitude increases?
Atmospheric pressure will decrease as altitude increases.
