+1 862 207 3288 A tank has a volume of 0.1 m3 and is filled with He gas at a pressure of 5 X 106 Pa. A second tank has a volume of 0.15 m3 and is filled with He gas at a pressure of 6 X 106 Pa. A valve connecting the two tanks is opened. Assuming He to be a monatomic ideal gas and the walls of the tanks to be adiabatic and right, find the final pressure of the system.
