Assume all gases are perfect unless stated otherwise. Unless otherwise stated, thermodynamic data are for 298.15 K. Calculate the final temperature of a sample of argon of mass $12.0 \mathrm{~g}$ that is expanded reversibly and adiabatically from $1.0 \mathrm{dm}^3$ at $273.15 \mathrm{~K}$ to $3.0 \mathrm{dm}^3$.
