Problem $5$:

A closed, rigid tank contains $5$ kg of air, initially at $300K,\frac{1}{b}ar.$ As shown in the figure below, the tank is in contact with a thermal reservoir at $600$ K and heat transfer occurs at the boundary where the temperature is $600$ K $.$ A stirring rod transfers $600$ kJ of energy $($by work$)$ to the air. The final air temperature is $600$ K $.$ The air can be modeled as an ideal gas with $c_v=0\mathrm{.}733k\frac{J}{k}g-K$ and kinetic and potential energy effects are negligible. Determine the amount of entropy transferred into the air and the amount of

entropy proauced witnin the air system, eacn in KJ$/$K$.$
