Abstract
P&V Independent involves the application of T&V independent together with the Application of second law of thermodynamics. The third TdS equation together with the first and second TdS equations has been known to many as the “tedious equations” due to a lot of derivations with resemblances involved. The TdS equations enables us to calculate the change of entropy during various reversible processes in terms of either dV and dT, or dP and dT, or dV and dP, and even in terms of directly measurable quantities such as the coefficient of expansion and the bulk modulus. This Manuscript involves another way of deriving the Thirds TdS equation applying the second law of thermodynamics together with equations already derived and introduced from the derivations of T&V which is also an application of the second law of thermodynamics.
