Atmospheric pressure changes with the weather. Cold air is heavier than warm air. Suspended particles or moisture will also increase pressure. http://en.wikipedia.org/wiki/Barometer

What is the relationship between altitude and atmospheric pressure?
the relationship between atmospheric pressure and altitude is the higher you go, the lesser the atmospheric pressure becomes. if the air above you is less, then there is less weight being pressed upon the air you are on. anonymous boy from small heath school y8 2011
Is it true that atmospheric pressure decreases with increased altitude?
False. The air pressure decreases and gets thinner as you go up. That is part of the reason why you can get nose bleeds as you go higher.
How does the air pressure change with increasing altitude?
Atmospheric pressure decreases with altitude. Weather conditions affect the pressure.

How does atmospheric pressure change with height above sea level?
Atmospheric pressure is the weight of the air above the surface of the earth. As elevation increases, there is less air above the location and the pressure is lower. At sea level the column of air above the area is greater.?æ
How does the boiling temperature of water change with altitude?
Depending on the altitude the boiling point will differ. This calculator will give you the boiling point of the altitude that you desire to discover: http://www.csgnetwork.com/h2oboilcalc.html
How does barometric pressure change with altitude?
Because pressure decreases as you go up in altitude and increases when you go down in altitude. Hope this helped!
What effect doe altitude and air pressure have on each other?
As you go higher, air (atmospheric) pressure gets reduced.

Does temperature change atmospheric pressure?
Yes, the hotter it is the more pressure, and therefore the colder the less pressure. Ther you go :)
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.
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.
Does the atmospheric pressure increase or decrease as you move upward away from sea level?
The pressure will decrease, fall, as your altitude increases. No it would not it would increase above sea level
Why do the boiling point of water decrease on climbing up the higher altitude?
Water usually boils at 212F or 100C at sea level. As you go higher up in the atmosphere (higher altitude), the amount of atmosphere pushing down on you decreases, hence the pressure decreases. Water boils when the vapor pressure of the water equals the atmospheric pressure. Vapor pressure increases with increasing temperature, so when there is less atmospheric pressure, a smaller vapor pressure is required to get the water boiling, hence a lower boiling temperature.
Why altitude affects boiling point?
Ya ........ if you have an egg on the top of high mountain the altitude and less air density causes lower boiling points and when you get higher it reduces the boiling point of the water and it is due to atmospheric pressure.Boiling is directly proportional to atmospheric pressure which becomes lower when we go above the sea level example mountainous areas.

How does atmospheric pressure change with height?
Think of the air pressure on any horizontal surface as the weight of all the air above it, all the way to the top of the atmosphere. As you increase altitude (go higher, on a mountain or in an airplane), there is steadily less atmosphere above you, and the air pressure steadily decreases with altitude.
How are density pressure and altitude related?
The higher you go, the lesser the air pressure becomes. This can be logically understood. Atmospheric air pressure is caused by the weight of the air above it. At greater heights, the amount of air above you is less, so there is less weight pressing on the air you are in. This is the reason why the atmospheric pressure is higher at the sea-levels and lower at mountains and places of high altitudes.
