Answer:

Hi. You have not informed the experiment that this question relates to, making it difficult to respond to your query. However, I looked up your query on the internet and found one similar to yours that included an experiment that measured the volume of balloons inflated by people's breath.

The <em>volume of the balloons remains constant throughout the number of tests</em>, according to the results of the experiment. This is due to the fact that when we blow, <em>our lungs prefer to express the same amount of air as when we breathe in</em> regular settings. This is most likely due to the fact that all of the balloons were filled with air when the participants were in the same physical and mental condition, i.e., calm and still, causing the volume of air they breathed and emitted to<em> remain constant</em>. If the individuals in the experiment were exerting some physical effort or were stressed and concerned, the amount of air would be different.
