How is air pressure created
Web1 jan. 2024 · Air pressure is created by the motion, size, and number of gas molecules present in the air. This varies based on the temperature and density of the air mass. In 1643, Evangelista Torricelli, a student of Galileo developed the mercury barometer to measure air pressure after studying water and pumps in mining operations.
