**Boyle’s Law**(Constant Temperature) is one of the three special cases of

**Ideal Gas Law**; the other two are

**Charle’s Law**(Constant Pressure) and

**Gay-Lussac’s Law**(Constant Volume). When this law is substituted with Charles’s Law and Gay-Lussac’s Law, develops into

**Combined Gas Law**; further combined with

**Avogadro’s Law**yields Ideal Gas Law.

**The above equation shows that when pressure increases the volume of the gas decreases in proportion.**

## Boyle’s Law Examples

### Mathematical Examples of Boyle’s Law

V1= 5 Litre

p2 = ?

where,

**6.25 atm.**

**2.**A balloon with a volume of 3.5 L is filled with a gas at 5 atmospheres. If the pressure of the balloon is reduced to2.5 atmospheres at a constant temperature. What will be the final volume of the balloon?

where,

p2 = 2.5 atm

V2 = ?

**x V2**

**7 Litre.**

## Examples Of Boyle’s Law In Real Life

**You Are Wrong**. Well, here is your chance to think again!!

There are several examples of Boyle’s Law In Real Life which is easy to understand or even you can do experiments related to them. let’s discuss a few of them one by one.

### The Mechanics Of Human Breathing

**pressure is inversely proportional to volume**“. As we all know the mechanics of breathing involve two different processes i.e Exhale and Inhale.

**air rushes inside the lungs**. On the other hand, when we exhale, the volume of the lungs decreases which in turn increases the pressure inside the lungs compared to the outer atmosphere, and as a result

**air rushes outside of the lungs**. Well, if you don’t believe me, check your self.
