Question
A rigid tank that contains 4.4 kg of N2 at 25°C and 550 kPa is connected to another rigid tank that contains 6.4 kg of O2 at 25°C and
150 kPa. The valve connecting the two tanks is opened, and the two gases are allowed to mix. If the final mixture temperature is 25°C,
determine the volume of each tank and the final mixture pressure. The gas constants of N2 and O2 are 0.2968 and
0.2598 kPa-m³/kg-K, respectively. The universal gas constant is 8.314 kPa-m³/kmol-K. Use the table containing the molar mass, gas
constant, and critical-point properties.
