Solution
Understanding the concept:
- Air is a mixture of various gases like nitrogen, oxygen,carbon dioxide, and helium and also includes water vapor.
- Inhaled air which we take in is called a fresh air rich of oxygen.
- Exhaled air is an air which we take out rich in carbon dioxide.
The explanation of water vapor:
- Water is formed when sugar (food) is broken by oxygen in respiration (along with carbon dioxide).
- As a result, exhaled air has significantly more water vapour than inhaled air.
Let's see if there's any water vapour in exhaled air.
- When we put a mirror in front of our mouth & exhale into it, water droplets will appear on the mirror's surface.
- This is due to the fact that during exhale, water vapour is released (breathing out).
- These water vapors are in more quantity than inhale air.
