What temperature scale is used in science?
Well, what temperature scale is appropriate....?
Several experimental gas laws established the dependence between a gaseous volume and temperature. And from the development of ideas of atoms and molecules, the experimental gas laws enabled chemists and physicists to form a pretty shrewd idea about the nature of gaseous particles...and of course from these ideas the molecular nature of matter, especially with regard to gases, were developed.
Most of the Gas Laws...
As a curiosity much of the gas laws owe to railway development....i.e. steam driven locomotives directly exploit gaseous pressure to provide motion...
