Why air exerts pressure ?
  • 1 answers

Amar Kumar 7 years, 11 months ago

Air is a mixture of gases, dust and other particles and water vapour etc.Air exerts pressure because its molecules are in constant motion they impact against objects they encounter and exert a pushing force against them. The force of multiple impacts over an area is air pressure. More air molecules from denser air will increase pressure, as will faster movement from high temperature.
