Entropy of interaction in the nuclei

  1. Mar 17, 2011 #1
    It's hard to me to understand about the interaction between protons and neutrons by the means of entropy. And Is it possible to know about an entropy of an interaction between protons and neutrons or between quarks:biggrin:?

    Look at the case of Nuclear Fusion. When nuclei fuse, they go to a lower energy state and release energy in the process. Once this happens, it requires energy to break them apart. The entropy of the system has increased.

    Thermodynamics was developed before anyone understood about atoms and molecules let alone sub-atomic structures. According to the thermodynamic definition of entropy, ds = dQ/T. Apply that to a system in which the source of heat flow is a nuclear reaction.
