Carbon dioxide $(C{O}_2)$ contained in a piston$-$cylinder arrangement, initially at $6$ bar and $400$ K $,$ undergoes an expansion to a final

temperature of $270$ K $,$ during which the pressure$-$volume relationship is $p{V}^{1\mathrm{.}15}=$ constant.

Assuming the ideal gas model for the $C{O}_2,$ determine the final pressure, in bar, and the work and heat transfer, each in $k\frac{J}{k}g.$

Part A$.$
