The twenty-eight essential results of the Bridgman formula method, according to a 1946 table by American physical chemist Samuel Glasstone. [5] |

Bridgman, in short, presented a clean and organized way of deriving thermodynamic expressions from the partial derivatives of the ten (or ten) main thermodynamic quantities (or variables),

In his 1925 "full version", in contrast to the 1914 "shorter version", of his systematic collection of thermodynamic formulas, he presented the first derivatives of the 10 fundamental quantities, which amounts to 720 equations, organized into 10 groups, based on which variable was held constant during the differentiation. [3]

Bridgman devised a system that allows for the derivation of any of these first partial derivatives in terms of three quantities which are, in general, capable of experimental determination, namely (∂V/∂T)P, (∂V/∂P)T, and (∂H/∂T)P, i.e. CP. The twenty-eight essential formulas derived using this methodology are show adjacent. [1]
