Abstract
The unattainability of the absolute zero of temperature is proved by using Carnot’s theorem. Hence this unattainability is distinct from the Planck-Fer-mi statement of the Third Law of Thermodynamics that the entropy vanishes at T =0. It is shown that the isothermal compressibility K T is in general larger than the adiabatic compressibility K s and the difference K T − K s vanishes in the low temperature limit.
