(a)
Air inside container Q is trapped and does not flow out. The air pressure inside container Q eventually stops and prevent the water from flowing into container Q.

(b)
The hole in the stopper allows air inside container P to flow out of the container. With less air inside container P, water can flow into the container and take up the space left by the air.

(c)
Make another hole in the stopper.
