Pressure of an ideal gas -- A Level Multiple Choice Problem

[QUOTE="jbriggs444, post: 6273684, member: 422467"] As I understand your work, you start by asserting: $$\frac{P_x2V_y}{150}=\frac{P_yV_y}{300}$$Where does this assertion come from? You then use the truth of that assertion to conclude that$$P_x=\frac{P_y}{4}$$But the fact that there is a tube connecting the two chambers indicates that in fact, ##P_x=P_y##. Your factor of four error is right there. [/QUOTE]
