Arigid, well-insulated tank of volume 0.9 m is initially evacuated. at time t = 0, air from the surroundings at 1 bar, 27°c begins to flow into the tank. an electric resistor transfers energy to the air in the tank at a constant rate for 5 minutes, after which time the pressure in the tank is 1 bar and the temperature is 457°c. modeling air as an ideal gas, determine the power input to the tank, in kw.
