I don't seem to understand Clausius inequality at all. Really. It was deduced to me that the Clausius inequality is given by(adsbygoogle = window.adsbygoogle || []).push({});

[tex]dS = \frac{\delta Q_i}{T} > 0[/tex]

where Q_i is the irreversible heat transfered to a system. Though I cannot find a way to prove an assertion my teacher said: through Clausius inequality, the irreversible heat to be transfered is lower or equal than through a reversible proccess.

It really doesn't make any sense to me, can anyone explain?
