#### Solution Preview

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.
