A tank with a volume of 3.5 m3 is filled with carbon monoxide at 53°C and 170 kPa is connected through a valve to another tank containing 3.6 kg of carbon monoxide at 100°C and 300 kPa. Now the valve is opened, and the entire system. If the final temperature of the entire system is 18°C, determine the volume of the second tank and the final equilibrium pressure of the carbon monoxide.
