A spring$-$loaded piston$$cylinder device contains a mixture of gases whose pressure fractions are $25$ percent Ne$,50$ percent O$2$O$2,$ and $25$ percent N$2$N$2.$ The piston diameter and spring are selected for this device such that the volume is $0\mathrm{.}1$m$30\mathrm{.}1$m$3$ when the pressure is $200$ kPa and $1\mathrm{.}0$m$31\mathrm{.}0$m$3$ when the pressure is $1000$ kPa. Initially, the gas is added to this device until the pressure is $200$ kPa and the temperature is $10$C$.$ The device is now heated until the pressure is $625\mathrm{.}0$ kPa. Calculate the total work and heat transfer for this process. The universal gas constant is Ru$=8\mathrm{.}314$kJ$/$kmol$$KRu$=8\mathrm{.}314$kJ$/$kmol$$K $.$ Use the table containing the ideal$-$gas specific heats of various common gases and the table containing the molar mass, gas constant, and critical$-$point properties. $($Round the final answer one decimal place.$)$
