1. a) Two tanks are connected by a valve. One tank contains 2 kg of CO2 at 400K and 70 kPa. The other tank holds 8 kg of CO2 at 250K and 120 kPa. The valve is Wened and the gasses are allowed to mix while receiving heat from the surroundings. The final equilibrium temperature is 310K. Assuming constant specific heats, calculate: 1. The final equilibrium pressure [4 marks] ii. Heat transfer for the process. [4 marks] S b) Complete the cells in the following table of properties of water. In the last column describe the condition of water as compressed liquid, saturated mixture or superheated vapour. If it is a saturated mixture, give the quality as well.
