Homework Help: Thermodynamics question

  1. Oct 18, 2006 #1
    hey guys got this question that i have been stuck on for a while.

    air is expanded from 1M Pa at 327 degrees celcius to 200kPa in a closed piston cylinder device. for the process PV^1.2 = constant. calculate the work done during this process

    any help will be welcomed

    temperature constant? work done= -pV ?

    if [P(V^1.2) = constant] this is an adibatic process which means that there is no heat added or taken away.

    I have not encountered something like V^1.2 before. Is that right? If so can someone enlighten me about it?
