A system consisting of 10 lb of air contained within a closed, rigid tank is initially at 1 atm and 600 R. Energy is transferred to the system by heat transfer from a thermal reservoir at 900 R until the temperature of hte air is 800 R. During the process, the temperature of the system boundary where the heat transfer occurs is 900 R. Using the ideal gas model, determine the amount of energy transfer by heat, in Btu, and the amount of entropy produced in Btu/R.
