Question
Which one of the following is the real-life example of Boyle’s law?
- Shrinking of the basketball
- Working of hot air balloon
- Human respiratory system
- Bursting of tyre
Hint:
It is an organ system.
The correct answer is: Human respiratory system
The correct option is c)Human respiratory system.
Our lungs use Boyle's law to breathe. When you inhale, your lungs fill with air. So they expand. As the volume increases, the pressure level decreases. Similarly, when air is expelled from the lungs, they contract. Therefore the volume decreases and the pressure increases. Pressure and volume changes are instantaneous and periodic in nature.
