(b) There are three vessels; A, B, and C which are connected together through some closed valves. The volume of each of vessels is 1.0 m³ and each of them contains similar gas at the temperature of 27°C. Furthermore, the pressure of the gas inside vessel A is 1.0 MPa, inside vessel B is 1.5 MPa and inside vessel C is 3.2 MPa. (1) (ii) Determine the mass of the gasses in each vessel. The valves are now opened, and the gases are allowed to mix. Determine the final pressure in vessels at the temperature of 27°C. Assume R for the gas to be 300 J/(kg K).
