The value of atmospheric pressure at Johannesburg?
85 kPa
What is the Standard pressure of a substance to become a gas?
Standard pressure is defined as 1atm, or 760mmHg. This is sea-level atmospheric pressure here on earth.
What is 760 mm atmospheric pressure?
760 mm Hg is 1 atmosphere, so approx 1 bar. It is 1.013 bar, which is 1013 milibars.
Why does atmospheric pressure changes as altitude increases?
the lower you go in relation to the top of the atmosphere the larger the column of air is that is pressing down on you. so if you are 3 ft from the edge of the atmosphere you only have 3 ft of air pushing on you but if you are at sea level you have thousands of feet of air pushing down.
How hot is 100'c with water?
It is the water boiling temperature under atmospheric pressure.
The value of atmospheric pressure at Johannesburg?
85 kPa
What is absolute pressure?
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
What is the value of atmospheric pressure?
about 100,000 newton per metre square. =)
If the absolute pressure of gas is?
Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
Is a line which represent continuous value on maps?
Isobar for atmospheric pressure, isotherm for temperature, or contour for height above (below) sea level.
Why do the lungs remain expanded in the normal thoracic?
A couple of reasons: surfactant - a detergent - reduces surface tension to a negative value. the plura contains a "vacume" (lower pressure than atmospheric) and pulls the lungs to the chest wall. venous blood partial gas pressure is sub atmospheric.
Why barometer points only to 76mmhg?
bacuse the experiment proved with the help of barometer..the value was 76mmhg.at wich the atmospheric presure and the pressure in vessel coincide...
What is the value of normal atmospheric pressure of oxygen?
The standard atmospheric pressure is the air pressure of 101325 pascals (Pa) or 101.325 kilopascals (kPa) (1013.25 millibars), exerted by a 760 millimeter (29.92 inches) column of mercury at sea level at a temperature of 0 degrees Celsius.
What is a math typical value?
The mean is that value that is most commonly referred to as the average.The typical value is a synonym for the mean and average.The typical value is the mean.
Is that the value for absolute pressure will always be greater than for gauge pressure?
No. We need to know exactly what is meant by gage here. A piston tyre gauge measures pressures relative to atmospheric. A mercury barometer measures absolute pressure. A gauge that involves uncoiling of a coiled tube will measure absolute pressure (it will have to be calibrated). But a manometer which is open to the atmosphere on one arm will measure pressures relative to atmospheric pressure so the real pressure is the two added together.
What is a typical effective cohesion value from negative pore water pressure in a uniformly graded loose medium sand?

Why is the value of atmospheric pressure compared to mercury?
Atmospheric pressure will support a column of mercury to about 760 mm. Mercurial air pressure is described as '760 mmHg'. As air pressure changes , the height of this column will also change. If you did it with water, the column would have to be about 34 feet (10.2 metres) in height.
