On an Absolute Thermometric Scale

On an Absolute Thermometric Scale

In famous publications, “On an Absolute Thermometric Scale founded on Carnot’s Theory of the Motive Power of Heat, and Calculated from Regnault’s Observations” is an 1848 article by English physicist William Thomson that introduced the absolute temperature scale a thermodynamic temperature scale starting at absolute zero degrees of temperature. [1] In the articles, Thomson derived the SI Kelvin temperature scale based on French physicist Sadi Carnot’s 1824 theory that the efficiency of any heat engine, i.e. the working ability any physical body whatsoever, depends only on the difference between the hot and cold reservoirs acting on the working body, in corroboration with 1847 experimental measurements of French chemist-physicist Henri Regnault.
