    Entropy change with angular momentum

    I am not sure about that, ozymandias. Absolute entropy of a system at equilibrium at temperature T(K) is said to be the integral of Q/T for T varying between 0K and T(K). So, you could, in theory, work it out once your system (e.g. a top, is at equilibrium at T(K)) is in equilibrium. But you...

    Entropy change with angular momentum

    ozymandias : I guess you could define a top entropy as the energy that could not be used to produce work. And that would conform to cesiumfrog's answer. I did not want to consider statistical thermodynamic. Therefore, the top would be a 0K with only one set of microstates. W=1, i.e...

    Entropy change with angular momentum

    Thanks CesiumFrog, From your answer: I gather that energy that is 100% convertible to work without loss (through friction I guess) can contribute to the entropy of the system. This is from a thermodynamic perspective. Am I correct? Now, when you say are you referring to Entropy...

    Entropy change with angular momentum

    Hello, I have a artist friend who designs spin tops. As we were discussing the physics (and the magic) of angular momentum and gyroscopic effects, the conversation drifted on entropy. We came up with this question: is the entropy of a spin top different when the top is at rest and when it...
