# Volume and pressure equivalence

Chemistry Level 2

A balloon is inflated with helium gas at room temperature of $$25^\circ C$$ and at $$1bar$$ pressure when its initial volume is $$3.0\text{ L}$$ and allowed to rise in air. As it rises in air external pressure decreases and volume of gas increases till finally it bursts when external pressure is $$0.3bar$$.What is the limit to which volume of the balloon can be inflated?

Given :
$$Pressure(1)=1bar$$ , $$Volume(1)=3.0L$$

$$Pressure(2)=0.3bar$$ ,$$Volume(2)=?$$
