Carbon dioxide $\left({\mathrm{CO}}_2\right)$ is compressed in a piston-cylinder assembly from $p_1=0.7$ bar, $T_1=280\mathrm{K}$ to $p_2=$ 12 bar. The initial volume is $0.3{\mathrm{m}}^3$. The process is described by $p{V}^{1.25}=$ constant. Assuming ideal gas behavior and neglecting kinetic and potential energy effects, determine the work and heat transfer for the process, each in $\mathrm{kJ}$, using constant specific heats evaluated at $300\mathrm{K}$, and data from Table $\mathrm{A}?23$.
