### What is one atmosphere?

A pressure measurement, in comparison to atmospheric pressure on Earth, at sea level, near sea level, at standard temperature, usually expressing an absolute pressure (but does not have to be). 1 atmosphere absolute = 1.01325 bar absolute 1 atmosphere absolute = 101,325 pascal absolute 1 atmosphere absolute = 14.69595 psi absolute

### What is the Formula of atmospheric pressure in relation to mercury column height in barometer?

The standard atmosphere (symbol: atm) is a unit of pressure and is defined as being precisely equal to 101.325 kPa. It is equivalent to 760 mmHg (torr) or 29.92 inHg. One standard atmosphere is standard pressure used for pneumatic fluid power (ISO R554), and in the aerospace (ISO 2533) and petroleum (ISO 5024) industries.

### How many minutes do you boil water to get to 100c?

The definition of 100 degrees Celsius is "the temperature at which water boils under a pressure of one standard atmosphere," so if it's boiling at that pressure it's ALREADY at 100 degrees C; no "minutes" are involved. Also, if you're at less than one standard atmosphere (you're in Denver or something) the water is not going to reach 100 degrees C no matter HOW long you boil it.

### What unit is pressure measured?

Pressure is often measure in units of force per area. In the standard system of units, the SI, that would be Newton / meter2 - this unit is also called Pascal. Other commonly used units are bar (equal 100,000 Pascal), and atmosphere (the atmospheric pressure under standard conditions - close to one bar).

### Is the vapor pressure of any substance at its normal boiling point equal to the atmospheric pressure?

The vapor pressure at the "normal" boiling point is 1 atmosphere. In everday life a substance will boil when the vapor pressure is the same as the local atmospheric pressure. Up a mountain water boils at a lower temperature. When there is high pressure area overhead then it boils at a slighly highrer temperature. The vapour pressure at the standard boiling point is 1 bar (100, 000 pascals) this is slightly higher than one atmosphere…

### What is the pressure per square inch on a person?

== == Zero or 14.7 pounds per square inch, take your pick. The atmospheric pressure is about 14.7 PSI (In REAL measurement systems that is about 101 kiloPascals). See: http://en.wikipedia.org/wiki/Atmospheric_pressure But the pressure ON a person comes from the inside AND the outside. So the pressure caused by the atmosphere ON a person is about zero. One often sees deep sea films where the commentator refers to the crushing pressure of seawater....Not for the animals…

### What is tire PSI?

PSI is an abbreviation that stands for Pounds per Square Inch.* For tires, it refers to the internal pressure of an inflated tire. * It expresses the unit for a pressure measurement (number of pounds on each square inch of surface area that is subject to the relevant pressure). This is a unit designation used primarily in USA and Canada. Other areas use the designations: kPa, standing for kilopascals, or, bar, the international metric unit…

### What is meant by the standard pressure?

One standard atmosphere is defined as a sea-level-extrapolated pressure of 1013.25 hectoPascals (millibars) at 0oC, or about 29.92" to use the most commonly-reported format. There is more to the standard atmosphere than this however - it also has other parameters such as temperature, density, etc., for a wide range of altitudes. It was established by the International Organization for Standardization in 1975. There are a couple of other 'standard atmospheres' floating around but all are…

### Percentage of oxygen at 10000 feet level?

The percentage of oxygen in the atmosphere does not change with altitude, so it is about 21% at 10 000 feet. What does change is the pressure. This declines with altitude. At sea level the air pressure is about 101 kPa (kilopascals). Oxygen accounts for 21% of this so the oxygen pressure is 19.6 kPa. This means that there are less oxygen molecules in the same volume of air at higher altitudes. At 10000 feet…

### How deep in water is 10atm of pressure?

Every 10 meters deep, the pressure increases by one atmosphere, approximately. Therefore, at 90 meters depth you would have, approximately, a pressure of 10 atm. (that is absolute pressure). Every 10 meters deep, the pressure increases by one atmosphere, approximately. Therefore, at 90 meters depth you would have, approximately, a pressure of 10 atm. (that is absolute pressure). Every 10 meters deep, the pressure increases by one atmosphere, approximately. Therefore, at 90 meters depth you…

### How do you convert from milliliters to kilo pascals?

Milliliters belong to the volume and capacity measures. Kilopascals belong to the pressure or stress measures. One cannot be converted to the other. I do not know the correct answer. However the questioner could be referring to millimeters of mercury which is a pressure measurement and would convert to pascals.

### Would a sample of gas in a closed container in space exert pressure on the sides of the container if the gas was kept at standard temperature and pressure?

Even if the pressure inside a container is equal to the pressure outside a container, there is still pressure. It's like pushing a friend one way while he pushes you back. Neither of you may be moving, but you're still pushing. The sample of gas would exert exactly one atmosphere of pressure (or 100 kPa) on the container. The question then becomes whether the container can withstand that pressure.

### A compound pressure gauge for the low side of the system measures pressure in what?

A compound pressure gauge measures two scales, one in positive pressure and one in negative (below atmospheric) pressure or vacuum positive pressure is measured in pounds per square inch (psi) or kilopascals or in some cases bars (1 bar = 14.35 psi) [ the average atmospheric pressure at 1000 feet above sea level] vacuum is measured in millimeters of mercury mmHg or inches of mercury inHg
