Homework Help: The gas is changing state?(q36)

  1. Nov 8, 2007 #1
    For this question:
    The answer is d.

    I am not sure what does it mean
    "The gas is changing state?"

    I refer to the book, a state variable can be pressure, volume, temperature and internal energy...So according to this understanding, can we understand as
    changing state = changing either pressure OR volume OR temperature OR internal energy OR any combination of those state variables?
