Reversible Processes

  1. Aug 24, 2010 #1
    Hi, this concerns thermodymanics.

    A block of volume V is reversibly compressed from pressure P1 to pressure P2 isothermally at temperature T.

    It goes on to ask about the heat expelled, but that's not my question.

    It is a solid, obviously not an ideal gas, so I'm sure the internal energy can change, yes?
    Also, what information can we deduce from the fact that it's a reversible process, if any?

    When a process is said to be 'reversible' (thermodynamically), then you're saying something very specific about the entropy of the process.

    Ah ha! The entropy doesn't increase, I see. Thanks!
