Question

A balloon is been blown up by a healthy person with no known respiratory disorder. Select the option that correctly provides information about the proportion of gasses of air inside the balloon compared to the proportion of gasses of air outside the balloon.
`{:(No,"water vapour","oxygen","carbon dioxide"),(1,"More","More","Less"),(2,"Less","More","More"),(3,"More","Less","More"),(4,"less","Less","More"):}`

Answer 1

The correct option is (3) "More","Less","More"

When a healthy person blows up a balloon, they are inhaling a mix of gases from the surrounding air, which is primarily composed of nitrogen (78%), oxygen (21%), and trace amounts of other gases such as carbon dioxide and water vapor. When they exhale into the balloon, they are expelling a mix of gases from their lungs, which is primarily composed of carbon dioxide (about 4.5%) and water vapor (about 0.5%), along with smaller amounts of oxygen and nitrogen. The proportion of carbon dioxide in the balloon will be higher than the proportion outside, the proportion of oxygen in the balloon will be less than the proportion outside and proportion of water vapour will remain same inside and outside.
