1 Gases Under Certain Conditions Of Pressure And Temperature Most Substances Can Exist In Any One Of Three States Of Matter Solid Liquid Or Gas For Example Water H 2 O Can Be Solid Ice Liquid Water Or Water Vapour Gas  Gas Is A Substance That Is Normally In The Gaseous State At Ordinary Temperatures And Pressures  Vapour Is The Gaseous Form Of Any Substance That Is A Liquid Or A Solid At Normal Temperatures And Pressures Thus At 25 0 C And 1 Atm Pressure We Speak Of Water Vapour And Oxygen Gas Gas Properties 1 Molecular Motion In Gases Is Random 2 2 Attraction Forces Between Gas Molecules Are So Small That Each Molecule Moves Freely And Essentially Independently Of Other Molecules 3 The Study Of Gas Behaviour As A Function Of Temperature And Pressure Play An Important Role In The Development Of The Atomic Theory
