Conceptual explanation for ΔS=Q/T

Click For Summary
SUMMARY

The equation ΔS=Q/T, which represents the change in entropy (ΔS) as a function of heat transfer (Q) and temperature (T), is grounded in empirical observation rather than intuitive understanding. The discussion emphasizes the need for a conceptual grasp of this equation, highlighting that it may not be immediately clear why it holds true. For a deeper understanding, readers are directed to the Physics Forums Insights Article on entropy and the second law of thermodynamics.

So understand how to solve a problem using the equation: ΔS=Q/T

But is there a conceptual explanation for why the equation works. And I'm not looking for a proof, but I simply want to understand why this equation should be intuitive.

Thanks for your time!

It's not that intuitive, and it is based on empirical observation.
