Question

What temperature scale is used in science?

Answer 1

Well, what temperature scale is appropriate....?

Explanation:

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.

Old `"Charles' Law"` established the proportionality of volume and temperature....i.e. `VpropT`...and this law proposed that there was a limit with regard to temperature...what today we would call `"absolute zero..."`. And thus at absolute zero, `-273.15` `""^@C` or `0*K` all molecular motion ceases (a simplification!), and this temperature represents the LIMIT of temperature...

Today `-273.15` `""^@C-=0*K`...the `K` stands for `"Kelvin Temperature"`, after William Thomson, later the Lord Kelvin (1824-1907)…

Most of the Gas Laws...`"Charles' Law"`, the `"Ideal Gas Law"` specify the use of the Kelvin scale...

As a curiosity much of the gas laws owe to railway development....i.e. steam driven locomotives directly exploit gaseous pressure to provide motion...
