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

    see attachment

    3. The attempt at a solution

    I'm having trouble where they multiply (101,000 by 1.5 m3)5/3

    I get 151,500 Pa*m5
    not 199,000 Pa*m5

    The adiabatic condition is:

    [itex]PV^\gamma = K[/itex] which means [itex]P^1 \times V^\gamma = K[/itex]

    Since [itex]\gamma = 5/3[/itex], and V = 1.5, [itex]V^\gamma = 1.5^{5/3} = 1.97[/itex]
