Quizplus · Accepted Answer

When the glass ball is in the pie pan, it displaces a volume of water equal to its weight. When the ball is removed and sinks, it displaces a volume of water equal to its volume, which is less than the volume displaced when it was floating. Therefore, the water level is lower.
