A well-insulated, rigid tank has a volume of 1 m3and is initially evacuated. A valve is opened, and the surrounding air enters at 1 bar, 27 °C. Heat is transferredto the tank by an electric resister at a constant rate for 5 minutes. After heating, the tank pressure is 1 bar and the temperature is 477 °C. Air can be modeled as an ideal gas. Find the power input required, in kW
