How high would the level be in an alcohol barometer at normal atmospheric pressure?
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1013 millibars.
"Barometric" (Atmospheric) pressure was always there in nature but Torrecelli invented the barometer to measure the atmospheric pressure using a barometer using a column of mercury. The normal atmospheric or barometric pressure at sea level is around 76 cm of mercury.
Pressure can be defines as a force acting normally on unit area of the surface. also mathematically pressure can be defined as : pressure= normal force/ area Atmospheric pressure decreases with altitude and is measured by barometer.
l4.7 pounds per square inches, or 30 Inches of Mercury- the normal barometer reading.
In Pascals in SI units. 100 kPa is about the atmospheric pressure at normal sea level. Can be considered roughly equal to 1 Bar, from the old mercury barometer measurement in mm of Mercury.
while the atmospheric pressure at mountain is 260mmhg
Mercury (Hg) is preferred in a barometer because it is very dense (13.6 times that of water). Normal atmospheric pressure at sea level will support a column of Hg nearly 30 inches tall. But it will support a column of water about 30 feet high. That would be a big barometer...
The atmospheric pressure is equal to the liquid's vapor pressure at that temperature.
Normal atmospheric pressure is abbreviated as atm. But when computing for the amount of total pressure exerted on an object at a specific depth or elevation, including normal atmospheric pressure, then the abbreviation ata is used. It stands for atmospheric pressure absolute.
Purely a matter of convenience. A water barometer is entirely feasible, but the column height at normal atmospheric pressure is over 32 feet tall. In order to make the barometer more compact, it's convenient to use the heaviest available liquid. Mercury has a little more than 13 times the density of water, so the column height in a mercury barometer is only about 30 inches tall, making for a much more manageable instrument.
Bar is a unit used to measure pressure, one bar is the normal atmospheric pressure of the on the surface of the earth, and ten bar is when the pressure is ten times the normal atmospheric pressure on the surface of the earth.
Standard atmospheric pressure is 101.325 kPa. It can also be quoted as 760 mm Hg, or 14,696 psi. Many values of atmospheric pressure are normal, because it varies all the time, but the average at sea level is 101.325 kPa.
The pressure of vapors is equal to the atmospheric pressure.
Boiling point is affected by air pressure. Normal means measured at normal atmospheric pressure.
Atmospheric Pressure - 100 000 Pa or 1 Bar
Under normal temperatures and pressure (for example room temperature and atmospheric pressure) tellurium is a solid.
The normal atmospheric gases, at low pressure.
In the mercury barometer, atmospheric pressure balances a column of mercury, the height of which can be precisely measured. Other liquids can be used in barometers, but mercury is the most common because of its great density (13.6 g/cm3). With a mercury barometer the column of fluid is only 760 mm high at normal atmopheric pressure, with water (with a much lower density of 1 g/cm3) it would have to be almost 10 m tall.
Point of a liquid is that temperature at which water vapor pressure is equal to the total atmospheric pressure?
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure at sea level, 1 atmosphere. The normal boiling point of water is about 100 degrees Celsius at a pressure of 1 ATM (i.e., 101.325 kPa). General Useful Information: The boiling point of a liquid is the temperature at which the vapor pressure of the… Read More
Atmospheric pressure is measured by a barometer and expressed in millibars. Normal atmospheric pressure at sea level is 1,013 millibars. Pressure is also measured in pascals, which is the pressure of 1 newton over 1 square meter. (A newton is the amount of force needed to accelerate 1 kilogram by 1 meter per second per second. 'atmosphere' itself is a unit , abbreviated as atm. 1atm=1.013 x 105. In the English system, pressure is measured… Read More
The normal boiling point (also called the atmospheric boiling point or the atmospheric pressure boiling point) of a liquid is the special case in which the vapor pressure of the liquid equals the defined atmospheric pressure at sea level, atmosphere
No Bromine is a liquid at room temperature and normal pressure
That would be slightly higher than the 'normal' atmospheric pressure of 1013mb
Atmospheric pressure. Oxygen
At normal atmospheric pressure & temperature propane is a gas.
Boost pressure is the amount of pressure above normal atmospheric pressure the turbo/supercharger is producing. Can be expressed in PSI (US used) or BAR (mainly outside the US). BAR = (boost pressure) * 14.7 (atmospheric pressure) / 14.7 (atmospheric pressure), an example 8psi of boost equals: 14.7+8/14.7 = 1.54bar
The air pressure on Earth is caused by the weight of the atmosphere pressing down. This pressure is also known as "atmospheric pressure". Normal atmospheric pressure at the surface of the Earth is 101 kPa, 760 mm Hg, or 14.7 psig
At normal atmospheric pressure 273 K.
At normal atmospheric pressure, it is a vapour.
At normal atmospheric pressure, at 100 deg C.
Compressed air does, but not air at normal atmospheric pressure
At room temperature and normal atmospheric pressure it is a gas.
Vapor pressure of a liquid at its normal boiling temperature is simply the atmospheric pressure, aka 1 atm, 760 torr, etc. This is by definition.
It depends on the pressure. At normal atmospheric pressure, the melting point of water is about 273.15 K.
It is the temperature at which a substance, under normal atmospheric pressure changes from the solid phase to the liquid phase.
Air pressure is greatest at or below sea level. Atmospheric pressure is the weight of air molecules pressing down on the surface as they are pulled by gravity. In very deep mines, the air pressure can exceed twice that at sea level.

Above 660.3 oC, aluminium is a liquid. Presuming normal atmospheric pressure.
Standard atmospheric pressure is equal to 760 mmHg. This is equal to 101.325 kPa, 29.92 inHg, 14.696 psi and 1013.25 millibars.
The human respiratory system would be most affected by a lower than normal atmospheric pressure because the air would be much thinner and therefore contain less oxygen.
Standard pressure (the "p" in STP) is 1 atmosphere or about 101 kilopascals (kPa). This is normal atmospheric pressure on planet Earth at sea level.
A liquid boils at a temperature at which its vapor pressure becomes equal to the pressure above its surface. Since you have increased the pressure to higher than normal atmospheric pressure, the water will not boil at 100oC, this is because the vapor pressure of the water at 100oC is now lower than the atmospheric pressure above the water's surface. In order for the water to boil its vapor pressure must be increased to at… Read More
Pure water, at normal atmospheric pressure freezes at 0 deg C. If the pressure is greater than normal atmospheric pressure (760mm of Hg) or if the water contains dissolved substances, its freezing point will be below 0 deg C.

Negative intrathoracic pressure is the normal pressure in the area between the pleura of the lungs and the chest wall. The pressure is considered negative because it is less than the atmospheric pressure.
