The stopcock between A and B is opened and the system is allowed to come to equilibrium. The pressur — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

At -73°C, water vapor completely condenses/freezes into ice $H_2O$(s) inside Bulb B. Both $CO_2$(g) and $N_2$(g) remain in the gaseous phase and distribute between bulbs A and B. Thus, bulbs A and B contain $CO_2$(g) and $N_2$(g), while Bulb B also contains the solidified water.
