In thermodynamics,

which is the quantitative measure of the "equivalence-values", or mechanical equivalent of heat changes associated with internal irreversible work process that exist at the end of one cyclical process or what are called "uncompensated transformations". This name "equivalence-value of all uncompensated transformations" was an early extended synonym for what would famously become termed as "entropy" in 1865.

**equivalence-value of all uncompensated transformations**, symbol*N*, is defined by the following expression:which is the quantitative measure of the "equivalence-values", or mechanical equivalent of heat changes associated with internal irreversible work process that exist at the end of one cyclical process or what are called "uncompensated transformations". This name "equivalence-value of all uncompensated transformations" was an early extended synonym for what would famously become termed as "entropy" in 1865.
