REAL LIFE APPLICATIONS OF BOYLE’S LAW

During respiration, our lungs make use of Boyle’s law. While inhaling, the lungs are filled with air; therefore, they expand.

The volume increases, hence the pressure level goes down. Similarly, when the lungs are evacuated of air, they shrink; therefore, the volume reduces and the pressure increases. The change in pressure and volume is momentary and periodic in nature.

A soda bottle, filled with a mixture of carbon-di-oxide and water, is one of the best examples to demonstrate Boyle’s law. When the soda can or bottle is sealed, it is difficult to compress. This is because the air molecules present inside the container are tightly packed and do not have space to move. When the can or the bottle is opened, some of the air molecules escape, thereby making space for the movement of air molecules and allowing the bottle to get compressed. Here, the change in pressure as per the change in volume can be clearly observed.
