The change in entropy in adiabatic process

  1. Nov 14, 2015 #1
    Hello everyone, I still wonder if there's a change in entropy in adiabatic process. The definition of entropy is a quantity represents for the disorder state of a system. Arccording to kinetic theory of gas, temperature is for the state of chaotic motion of molecules. So I'm very confuse, can someone explain for me without using the entropy equation ΔS=∫dQ/T ???
    Thanks a lot!!!

    If the adiabatic process is reversible, then the entropy doesn't change. If the adiabatic process is irreversible, the entropy increases. There, I didn't use the equation.
