Question

what is atmospheric pressure ?​

Answer 1

Explanation:

Answer:

Atmospheric pressure, sometimes also called barometric pressure (after the sensor), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 1,013.25 mbar (101,325 Pa; 1,013.25 hPa), equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth, that is, the Earth's atmospheric pressure at sea level is approximately 1 atm.
