Question

Please answer quickly and correctly​

Answer 1

Explanation:

When the rubber sheet is pushed upwards into a dome shape, the balloons become deflated. This is because the air volume inside the bell jar decreases, thus increasing the air pressure. As a result, the volume of the balloons decreases and the pressure increases. Air is forced out of the balloons.

Answer 2

Explanation:

Ballons are equivalent to lungs .

Rubber sheets are equivalent to diaphragm.

As the rubber sheet is pulled down the volume of the jar increases, the pressure therefore decreases and air is drawn in through the glass tube inflating the balloons, which represent the lungs.
