Generally, atmospheric pressure is greatest at ground level, because you are at the bottom of the 25 mile thick atmosphere of earth. Greatest water pressure in a swimming pool is at the bottom, too. As you go up into the atmosphere, the pressure tends to decrease.
If you mean height above the Earth's surface, atmospheric pressure varies inversely with altitude.
How does liquid pressure vary with depth
the shape and height causes it to vary with temperature,pressure,and the amount of water vapor in the atmosphere
As altitude increases, atmospheric pressure decreases.
As with anywhere, the atmospheric pressure in Arizona is variable. However, it does not vary much from the standard 13.7 pounds per square inch.
Changes in air temperature or humidity cause air pressure to vary. An increase in air pressure causes the mercury to rise; a decrease causes the mercury to fall.
It increases the lower you go in the atmosphere. In simple terms, there is more air pushing down on lower altitudes. Pressure will, of course, vary with weather conditions.
As temperature increase pressure will increase
stupid question mr miller
Atmospheris pressure varies above the sea level .With the change in the atmospheric pressure the boiling point of water also changes.With the increase in pressure the boiling point of the water increases and with the decrease in the pressure the boiling point of the water decreases.
It will vary slightly with changes in atmospheric pressure, but is approximately 472ºF.
No, but it will vary very slightly with atmospheric pressure.
Gas, the actual values vary with temperature and pressure. The entropy of H20 gas at standard atmospheric pressure is about 7.35 kj/kg*k and H20 liquid at 1 atmosphere is about 1.3 kj/kg*k.
In liquids, pressure varies with depth. As the depth or height increases, the pressure applied by the liquid also increases. This can be related using a formula: Pressure in liquids= density*height*gravitational pull.
I believe a better way to ask this question is "how does atmospheric pressure vary with altitude?" I refer you to this page on wikipedia: http://en.wikipedia.org/wiki/Atmospheric_pressure#Calculating_variation_with_altitude Here you will find the proper equation.
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
Winds or breezes are caused by atmospheric pressure. When air is heated by the Sun, it warms and becomes less dense. This means that the parts of the air column making up the atmosphere vary between areas of warm air and areas of cold air. Areas of warm air are less dense and therefore have a low pressure as compared with areas of cold air which have a high pressure. To even out the pressure difference, the air flows from areas of high pressure to areas of low pressure and this flow of air is called the wind.
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.
Every 10 meters you go down, the pressure increases by approximately 1 atmosphere or 1 bar.
I must assume you mean uniterrupted column of water! The maximum suction lift of a column of water is the height of a column of water (inside a vertical pipe for instance) that can be supported by atmospheric pressure i.e. approx 14.69psi or 760mm Mercury. You should be aware that suction does not cause water to lift. Suction produced by various kinds of pump merely removes air from above the column of water and this allows atmospheric pressure to act upon the base of the water column. The water column is therefore pushed upwards by atmospheric pressure from below rather than pulled up by suction from above. The density, vapour pressure and surface tension of water vary slightly with temperature and atmospheric pressure also varies slightly with weather conditions. Thus the measured height of the water column may vary slightly according to the conditions prevailing when making the measurement. A good approximation at room temperature is 33 feet or 10 metres.

in atmospheric pressure water evaporates at 100 degrees Celsius and freeze at 0 degrees Celsius. This may vary based on pressure
Terminal velocity is determined by the object's shape, weight, and density of the atmosphere. Weight and atmospheric density can vary depending on where you are.
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.
The simplest method would be to mount a pressure gauge onto the chamber, then to observe whether the reading changes. It should remain at "zero" indicated gauge pressure. If your instrumentation is relative to atmospheric pressure, it would be a "minus" pressure and would vary with local atmospheric pressure. For very accurate readings, you would need something more sophisticated, such as an ionisation gauge.
At sea level,the pressure of the atmosphere pushing down on the ocean surface is reffered to as 1 atmosphere of pressure.An atmosphere is the pressure exerted on a surface at sea level by the column of air above it.As you go below the oceans surface ,the pressure increases because of the force of the water molecules pushing down.
