Question

02 multiple choice
what happens to the small balloon when the large balloon is pulled downward?
a) the small balloon deflates (gets smaller)
b) the small balloon stays the same size
c) the small balloon inflates (gets bigger)
d) the small balloon bursts
03 multiple choice
what happens when the large balloon is pushed inward?
a) air pressure inside the cup increases
b) the space inside the cup gets larger
c) air pressure inside the cup decreases

Explanation:

Question 02

This is a model of the respiratory system (like lungs and alveoli). When the large balloon (representing the diaphragm/chest cavity) is pulled down, the volume inside the "chest" (the space around the small balloons) increases, so air pressure decreases. Air then moves into the small balloons (representing alveoli) from higher - pressure areas (outside or the "trachea" part), making them inflate. So the small balloon gets bigger.

When the large balloon (diaphragm/chest cavity) is pushed inward, the volume of the space inside the cup (chest cavity) decreases. According to Boyle's law (for gases, at constant temperature, pressure and volume are inversely related), as volume decreases, the air pressure inside the cup (which is like the pressure in the chest cavity) increases. Option B is wrong because pushing the large balloon inward decreases the space.

Answer:

C) The small balloon inflates (gets bigger)

Question 03 (assuming the options are about pressure and volume changes, typical of respiratory or gas laws models)
