That's just circular : it's a self description.
This pressure, of nearly one atm., is basically the atmospheric pressure which exists at sea level.
I'll assume you mean atmospheric pressure, which is generally stated to be 101,325 Pascals... 101,325 Pa 101.325 kPa 760 torr 760 mmHg 1 ATM 1 bar
84 x 0.00986 = 0.82824 atm=========================Explanation:'Standard' atmospheric pressure is defined as 101.325 kPa.84 kPa is 84/101.325 = 0.82902 standard atm pressure
It just means that the pressure you're measuring is approximately the same as Earth's air pressure at sea level.
The balloon exists in a separate pressure system from the bell jar itself.As the balloon is open to the surrounding air, the pressure within the balloon is 1 atm (1 atmospheric unit of pressure = 105 Pa).When pressure is decreased within the jar, the pressure within the jar decreases to a value lower than 1 atm. Therefore, to counter the low pressure created in the jar, the atmospheric air moves into the balloon and pushes the balloon into the jar to attempt to equalize the pressure in the balloon and in the jar. Therefore the balloon inflates.
ATM stands for atmosphere, such as in atmospheric pressure.
This pressure, of nearly one atm., is basically the atmospheric pressure which exists at sea level.
1 atm (standard atmospheric pressure) is 101,325 kPa.
1 atm (standard atmospheric pressure) is 101,325 kPa.

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.
It's a measure of pressure. Specifically, it's the amount of pressure exerted by the air in the atmosphere at sea level.
At the standard atmospheric pressure of 101325 Pa water boils exact at 100 degrees Celsius.
14.7 psia represents standard atmospheric pressure, or 1 atm. PSIA is just psi with atmospheric pressure taken into account also.
