To determine what happens to the balloon when the air in the bell (presumably a chamber or container) is removed with a pump, we need to understand the relationship between pressure and volume.
When the air inside the bell is removed with a pump, the pressure inside the bell decreases. According to Boyle's Law, as the pressure of a gas decreases, the volume it occupies increases, provided the temperature remains constant.
So, when the air is removed from the bell, the pressure decreases, causing the balloon to expand. The correct answer is B: expanded.
