Thermodynamics: Irreversible process and entropy

  1. Apr 3, 2016 #1
    1. The problem statement, all variables and given/known data
    Hi !

    I'm stuck with these two questions of my assignment of thermodynamics

    - Give two exemples of irreversible process (initial state, process, final state)
    - For each of them, explain why they are irreversible on the microscopic scale.

    2. Relevant equations
    We are not asked any calculations here. I only need to describe with a few sentences.

    3. The attempt at a solution
    irreversible process => exemple : An engine (?) There's an irreversible process because of the Joule heating and frictions.

    An irreversible thermodynamic process for an arbitrary system is one during which the system and surroundings are not in equilibrium. So think of any real process.
