Final answer:Without specific details such as volume changes or the mass of argon, it's not possible to directly calculate the work and heat transfer in the given polytropic compression scenario.Explanation:Argon is compressed in a polytropic process with n=1.2 from 120 kPa and 10 °C to 800 kPa in a piston cylinder device. Asking to determine the work produced and the heat transferred during this compression process requires the use of the polytropic process equation and thermodynamic relationships. Unfortunately, without additional specific details such as the volume changes or the mass of argon being compressed, it is not possible to directly calculate the work done and heat transferred for this scenario. These calculations typically involve using the polytropic equation PV^n = constant, alongside the first law of thermodynamics for a closed system (ΔU = Q - W), with the properties of argon (specific heats, etc.) to find the final volume, the change in internal energy, and subsequently the work and heat transfer. For a direct solution, additional data or assumptions about the volume or mass of argon are needed....
