14.4: Entropy

Example. Now let us take a look at the change in entropy of a Carnot engine and its heat reservoirs for one full cycle. The hot reservoir has a loss of entropy ΔSh=−Q h /T h, because heat transfer occurs out of it (remember that when heat transfers out, then Q has a negative sign).The cold reservoir has a gain of entropy ΔS c =Q c /T c, because heat transfer occurs into it.

Why does the nature always prefer low energy and maximum entropy?

In this case it''s the maximum entropy principle you mentioned (also known as second law of thermodynamics). This law tells that the system will try to maximize it''s entropy. The consequence is that all the energy will try to convert into thermal energy (heat) thus increasing the entropy. Now you run into next question - why maximum entropy?

What are entropic forces and how are they related to free energy

Feb 10, 2021· Entropic forces are "effective" forces that spawn out of entropy maximization: if your system is a in a low entropy state and can evolve into a higher-entropy one, there will be a push ("force") towards a higher entropy state. The reason is that the free energy contains an entropy-term which can give rise, upon derivation, to a force.
