Homework Help: Maximum Temperature

  1. Jul 17, 2010 #1
    Again, it's a translation, i don't know if it's 100% accurate in english

    1. The problem statement, all variables and given/known data

    An ideal gas suffers a transformation under the law [itex]p=p_0-aV, p_0=10^5 Pa, a=\frac{10^6}{8,3} \frac{Pa}{m^3}[/itex]. The maximum temperature on this transformation is: ...

    A) 2450 K
    B) 2500 K
    C) can't be calculated (THIS IS NOT THE ANSWER)
    D) 2480 K
    E) 2490 K
    F) 2460 K

    2. Relevant equations

    [itex]\frac{pV}{T}= ct[/itex]

    3. The attempt at a solution

    The attempt? Nill...not even my physics teacher could solve this (private lesson with him). And i really don't have any ideea...

    That [itex]aV[/itex] is actually another pressure...

    Substitute p(V) from the equation to the ideal gas equation to obtain T(V). For V>0, find max(T) :smile:

    EDIT: I think the number of moles of the gas must be given for a numerical value of Tmax.
