Abstract

Abstract: By using the experimental data of air，hydrogen，nitrogen，oxygen and carbon dioxide in the

standard state in Handbook of Physical Chemistry and combining with error analysis，we verify partially the

correctness of the thermodynamic formula of C_p - C_V = pTVαβ in pVT system. Accordingly，the reliability of the related

thermodynamics theory and mathematical reasoning process are confirmed.

Key words: constant pressure heat capacity, constant volume heat capacity, standard condition, data, error
