 # Which Of The Following Is Equal To 1 Atm Pressure?

## Which of the following is equivalent to 1 atm pressure?

The standard constant value used for atmospheric pressure at sea level is 1 atm (standard atmosphere) which equals 101325 pascals in SI units, and is equivalent to 29.9213 inches of mercury..

## What is atmospheric pressure in simple words?

That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer. … Meteorologists describe the atmospheric pressure by how high the mercury rises.

## What is the value and unit for standard pressure?

Standard Temperature and Pressure. Standard temperature is equal to 0 °C, which is 273.15 K. Standard Pressure is 1 Atm, 101.3kPa or 760 mmHg or torr.

## What is ATA full form?

Stands for “Advanced Technology Attachment.” It is a type of disk drive that integrates the drive controller directly on the drive itself. Computers can use ATA hard drives without a specific controller to support the drive.

## How many MB is low pressure?

1000 mbPoints above the 1000 mb isobar have a lower pressure and points below that isobar have a higher pressure.

## What is Ata in Pressure?

= 1 ata (atmosphere absolute). The ata unit is used in place of atm to indicate the total pressure of the system, compared to the pressure of the medium vs vacuum only. For example, underwater pressure of 3 ata would mean that pressure includes 1 atm of air above water and also 2 atm of water itself.

## What is the formula for atmospheric pressure?

Atmospheric pressure is the pressure caused by the mass of our gaseous atmosphere. It can be measured using mercury in the equation atmospheric pressure = density of mercury x acceleration due to gravity x height of column of mercury.

## Is 1 atm a standard pressure?

Another commonly used unit of pressure is the atmosphere (atm). Standard atmospheric pressure is called 1 atm of pressure and is equal to 760 mmHg and 101.3 kPa. Atmospheric pressure is also often stated as pounds/square inch (psi). The atmospheric pressure at sea level is 14.7 psi.

## What is the standard atmospheric pressure?

Standard atmospheric pressure is usually taken to be 0.760 m Hg at 0°C. This is a pressure of 101 325 Pa.

## What is the normal atmospheric pressure?

about 14.7 pounds per square inchThe standard, or near-average, atmospheric pressure at sea level on the Earth is 1013.25 millibars, or about 14.7 pounds per square inch. The gauge pressure in my automobile tires is a little more than twice that value.

## Is pressure a unit?

PascalPressure/SI unitsThe SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2). This name for the unit was added in 1971; before that, pressure in SI was expressed simply in newtons per square metre.

## What is standard atmospheric pressure in ATM?

101.325 kilopascalsStandard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

## What is r in pV nRT?

Pressure is inversely proportional to volume: = , where a > 0 is a constant. … The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K.

## What do you mean by 1 atm pressure?

It corresponds to the pressure exerted by a vertical column of mercury (as in a barometer) 760 mm (29.9213 inches) high. One standard atmosphere, which is also referred to as one atmosphere, is equivalent to 101,325 pascals, or newtons of force per square metre (approximately 14.7 pounds per square inch).

## Is 1 bar the same as 1 atm?

Bar and Atm are the units representing pressure….What is the Relation Between Bar and Atm?Bar to atm formula1 bar = 0.986923 atmatm to bar formula1 atm = 1.01325 bar
