3. Nitrogen (N₂) is pumped into a closed, rigid, 8.5 ft³ tank with a paddle wheel at 50 °F and 16.7 lbf/in². During a process, the paddle wheel transfers 8 Btu of energy to the gas through work. At the completion of the operation, the gas temperature hits 100 °F. Calculate the mass of nitrogen in lb and the heat transfer in Btu, considering N₂ as a perfect gas. The effects of kinetic and potential energy can be ignored. (20 points)
