  2. What happens to the volume? If there is no volume change there is no work done. If the volume increases, then the system has done work to the outside and work is negative.

  5. Old question, but I just want to make sure the correct answer is given.

    Work when being compressed in negative and when being expanded is positive. When work is negative it is being done TO the system and when positive is being done BY the system.

    So the correct answer is that work is negative and is done to the system.
