Question
The figure given below shows three glass chambers that are connected by valves of negligible volume. At the outset of an experiment, the valves are closed and the chambers contain the gases as detailed in the diagram. All the chambers are at the temperature of 300K and external pressure of 1.0 atm.
Suppose that both valves opened, the entire apparatus is cooled to lower the final internal pressure to 1.0 atm. What is the contribution of 
gas to this final pressure?
- 0.40 atm
- 0.35 atm
- 0.30 atm
- 0.25 atm
The correct answer is: 0.30 atm
