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 `300 K` and external pressure of `1.0 atm`.
What will be the work done by `N_(2)` gas when valve `2` is opened and value `1` remains closed?
A. `8.2 L atm`
B. `-8.2 atm`
C. `0`
D. `3.28 L atm`
