In the 1720s the English cleric and natural philosopher Stephen Hales demonstrated that atmospheric air loses its spring (i.e., elasticity) once it becomes fixed in solids and liquids. Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.

John Dalton Biography & Atomic Theory | What did John Dalton Discover? What Was Lavoisier'S Greatest Contribution To Science It stated that matter couldn't be created or destroyed. It was previously claimed that the elements were distinguishable by certain physical properties: water and earth were incompressible, air could be both expanded and compressed, whereas fire could not be either contained or measured.
