hi friends.... In the entropy chapter of thermodynamics it has been formulated that (Integral of dQ/T) for a irreversible process < S2 - S1 i.e the change in S; my doubt is how do they find the value of (Integral of dQ/T) for an irreversible process in the first place??? For a reversible process the value can be found by replacing the entire process by infinitesimally small alternate adiabatic and isothermal processes. But the same approach cannot work for an irreversible process, can it?? Can anyone please consider and answer my query.... Thanx in advance..... ALL THE BEST for GATE 2007!!!
