# What temperature scale is used in science?

Jun 18, 2018

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 $\text{Charles' Law}$ established the proportionality of volume and temperature....i.e. $V \propto T$...and this law proposed that there was a limit with regard to temperature...what today we would call $\text{absolute zero...}$. And thus at absolute zero, $- 273.15$ ""^@C or $0 \cdot K$ all molecular motion ceases (a simplification!), and this temperature represents the LIMIT of temperature...

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

Most of the Gas Laws...$\text{Charles' Law}$, the $\text{Ideal Gas Law}$ 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...
