A spring$-$loaded piston$-$cylinder device contains $5$ kg of a gas as the system. This system is heated from $100$ kPa and $20C$ to $800$ kPa and $160C.$ Determine the heat transferred to and the work produced by this system. $)=2\mathrm{.}0769\frac{kJ}{k}gK,c_v=3\mathrm{.}1156\frac{kJ}{k}gK,c_p=(4\mathrm{.}1156\frac{kJ}{k}gK.$
