Inexact differential Totally Explained

Everything about Inexact Differential totally explained

In thermodynamics, an inexact differential or imperfect differential is any quantity, particularly heat Q and work W, that are not state functions, in that their values depend on how the process is carried out. The symbol, or δ (in the modern sense), which originated from the work of German mathematician Carl Gottfried Neumann in his 1875 Vorlesungen uber die mechanische Theorie der Warme, indicates that Q and W are path dependent. Continuing with the same instance of

Delta Q

, for example, removing the

, the equation ť :::

Q = int_C_p,dT ,!

is true for constant pressure.
