Homework Help: Work done by non-ideal gas

  1. Oct 23, 2007 #1
    1. The problem statement, all variables and given/known data

    For some particular unusual non-ideal monatomic gas, take the relation beween P and V at some fixed To to be
    P = Po(Vo/V)1/2.
    Let To = 100 K, Po = 100000 Pa, and Vo = 0.1 m3.

    2. Relevant equations

    How much work does this gas do if it expands, pushing on a piston, from Vi = 0.3 m3 to Vf = 0.44 m3 at T = 100 K?

    3. The attempt at a solution

    Someone please help!?!
    I don't understand non-ideal gases.

    Even though you don't know much about non-ideal gases, that doesn't mean you can't do anything here. Give me some of your thoughts on the problem. Here's a hint to get you started thinking:

    What is the definition of work done by a gas? This should still apply to this non-ideal gas, correct?
