I have read a post that interests me greatly Heat engines and "Angular momentum" engines?
I have often wondered what the relationship is for example between Conservation of Angular Momentum and Entropy
I have a simple system with two possible (but not equally probable) microstates consisting of 8 particles contained in a circular boundary
However Conservation of Angular Momentum tells me that the Angular Momentum of the system (Positive L ) must be conserved so I will not evolve to the disordered system (L= Zero) without an external force (torque)
This to me makes sense as without an external force the sum of the counter and counterclockwise vectors can not change.
However if the system can exchange heat with its surroundings then the vectors can change (thru Maxwell Diffuse Reflection) and evolution to the disordered state is possible.
The problem is that the interaction of heat at the boundary is normal to the surface so is not a torque but provides a deceleration that changes the amount of Angular Momentum ?
How can I bring these two laws together. Are they one and the same thing as suggested by @Nathaniel ?
i am seeking an intuitive answer as my calc is greatly deficient
