Atank of 0.1-m3volume contains air at 298.15K (25°C) and 101.33kPa.The tank is connected to a compressed-air line which supplies air at the constant conditions of 318.15K(45°C) and 1500kPa. A valve in the line is cracked so that air flows slowly into the tank until the pressure equals the line pressure. If the process occurs slowly enough that the temperature in the tank remains at 298.15K(25"C), how much heat is lost fromthe tank? Assume air to be an ideal gas for which Cp=(7/2)R and Cv=(5/2)R
