Homework Help: Isobaric process

  1. May 8, 2008 #1
    [SOLVED] Isobaric process

    Hi, need some help with this.

    I got to moles of an ideal gas that are heated at constant pressure from T=27 C to T=107C.

    How do I calculate the work done by the gas?

    I know that for a isobaric process the work is given by

    W = p(V2-V1)

    Thanks

    P.S. We have Homework & Coursework forums for textbook questions.

    Oh, I'm sorry. Yeah, I tried W = nRT.

    Came out with 1300 J, but the key book says 1330 J.

    Using [itex]W = nR\Delta T[/itex], my answer agrees with your text. I would suggest you re-check your calculations.

    There, it worked.
