    The first law of thermodynamics says:

    U2 -U1 = Q -W
    W = P(v2-v1)

    m = 0.1 kg of argon
    T1 = 4900 K
    V1 = 40 LT
    V2 ...

    Solution Summary

    The solution provides a step-by-step explanation of how to find the boundary work and final temperature in a piston cylinder after the gas undergoes an isobaric process using the first law of thermodynamics.
