Is 0 mm hg equal to 0 psia and is 760 mm hg equal to 0psig?
0 mmHg is equivalent to 0 psia because both represent a pressure of zero relative to absolute vacuum. However, 760 mmHg is equal to 14.7 psia, not 0 psig. 760 mmHg is equivalent to atmospheric pressure, which is the reference point for psig.
Is the air pressure at Sea Level 700 mm of Hg?
Standard Air Pressure is 760 mm Hg (or 29.92 in)
Expressed in mm of mercury?
Pressure, in particular atmospheric pressure.
A gas thermometer registers an absolute pressure of 305 mm of mercury when in contact with water at the triple point. A) What pressure does it read when in contact with water at the normal boiling poi?
At the normal boiling point of water (100°C), the vapor pressure of water is approximately 760 mm of mercury (1 atm). The gas thermometer, which measures absolute pressure, would read the sum of the atmospheric pressure and the vapor pressure of water. Therefore, if the thermometer initially reads 305 mm of mercury at the triple point, at the normal boiling point, it would read 760 mm of mercury.
Why is 760 mm hg equal to 1 atmosphere?
Oh, dude, it's like this science thing where they decided that 760 mm Hg is the same as 1 atmosphere. I mean, who even measures pressure in millimeters of mercury anyway? But yeah, they just agreed on it, so now we all gotta go along with it. Science, man, it's a trip.
What is the mean of 760mm of hg?
760 mm Hg is the standard barometric (atmospheric) pressure. It is the pressure giving a pillar of mercury (the elemental abbreviation of mercury is Hg) that is 760 millimeters (mm) high.
A gas occupies 30 L at 760 mm Hg what is its volume at 350 mm Hg?
The phrase "760 mm Hg" is physicists' shorthand for "an atmospheric pressure equal to that needed to support a column of mercury [chemical symbol Hg] of length 760 mm". This is approximately average atmospheric pressure at sea level. As the pressure decreases from "760 mm Hg" to "350 mm Hg", the volume of the gas will increase (assuming a constant temperature). The new volume can be determined using Boyle's Law: New Volume = 30 x 760 / 350 = 65.143 Litres
Is 0 mm hg equal to 0 psia and is 760 mm hg equal to 0psig?
0 mmHg is equivalent to 0 psia because both represent a pressure of zero relative to absolute vacuum. However, 760 mmHg is equal to 14.7 psia, not 0 psig. 760 mmHg is equivalent to atmospheric pressure, which is the reference point for psig.
How many mm of mercury in an atmosphere?
This is an old measurement, but 760 mm is one atmosphere.
What is the partial pressure of oxygen in blood gas a mixture of N2 O2 and CO2 if the partial pr. of Nitrogen 630 mm of Hg and partial pressure of CO2 is 39 mm of Hg?
To find the partial pressure of oxygen, we need to subtract the partial pressures of nitrogen and CO2 from the total pressure of the mixture, which is typically around 760 mmHg at sea level. Therefore, the partial pressure of oxygen would be 760 - 630 - 39 = 91 mmHg.
Normal atmospheric pressure is enough to support a column of mercury approximately?
Standard pressure is the pressure exerted by a column of mercury exactly 760 mm high. This is called one atmosphere and is approximately the average pressure at sea level.
How do you convert 720mmHg to ATM?
Convert mmHg to ATM using 1 ATM = 760 mmHg as a conversion factor.
The atmospheric pressure at the summit of MtMcKinley is 606 mm Hg on a certain day What is the pressure in ATM and in kPa?
The standard atmospheric pressure is 14.7 psi which is equal to 1014 millibars and 760 mm Hg. Therefore 606 mm Hg = 606/760 of an atmosphere = 0.797 atm. Therefore in millibars it is 0.797 x 1014 = 808.5 mb. Now 1 mb = 100 Pa = 0.1 kPa, so 808.5 mb = 80.85 kPa.
How do you convert MmHg to Pascal?
How do you convert mm Hg to pascal?Answer1 mm Hg = 133.322 Pa760 mm Hg = atmospheric pressure = 101325 Pa133.322 times 760 mm Hg = 101325 Pa
Is the air pressure at Sea Level 700 mm of Hg?
Standard Air Pressure is 760 mm Hg (or 29.92 in)
What is the pressure in mm Hg of a gas at 2atm?
1 atm of pressure equals 760 mm Hg, so 2 atm = 1520 mm Hg.
What is the atmospheric pressure when there are land breezes?
A breeze hardly changes pressure, rather it is pressure gradients that cause breezes - wind. So in "breezy weather the pressure is "normal" : or close to ---> 760 mm HG or 1000 bar or 29.92 inches of Hg.
