Conceptual polytropic question

  1. Sep 21, 2015 #1
    1. The problem statement, all variables and given/known data
    Can someone give me an explanation of a polytropic process and maybe an example? I know it obeys pvn=constant, but I can't seem to find a definition that makes this concept click in my head.
    Would you consider isobaric, isothermal, and isochoric processes to be polytropic?

    For isothermal I think n=1? so then pv=constant? and pv=T?

    Thanks for any help!

    2. Relevant equations


    3. The attempt at a solution

    A polytropic process is carried out reversibly, and both the temperature and the volume (or pressure) are varied simultaneously along the process path in such a way that pvn is constant. For a constant pressure situation, n = 0, for an adiabatic situation, n = γ, and for an isothermal situation, n = 1.
