9. Carbon Dioxide and Oxygen is placed each inside a 1m3 tank separated by an isolation valve. Initially, Carbon dioxide has the following properties: P = 20kPag & T = 25°C and that Oxygen has the following properties: P = 30kPag & T = 75°C. If heat is being prevented to escape in the outside surroundings, determine the resulting temperature of the mixture if it is found that after opening the isolation valve, the resulting pressure on both tank is 25kPag. Draw a figure or FBD that will support the problem. Explain each step by step formula.
