A closed, rigid tank whose volume is 1.3 m3 contains 3.22 kg of air with the initial conditions of 260 K and 185 kPa. A paddle wheel within the tank does work on the air inside the tank, and 45 kJ of energy escapes through the walls by heat transfer at an average temperature of 285 K. Assuming that air in the tank is an ideal gas with a gas constant of Rair, 1. Determine the final temperature of the air, in K. 2. Determine the heat transfer between the tank contents and the surroundings, in KG.
