Question

A balloon is filled with hydrogen at room temperature. It will burst if pressure exceeds 0.2 bar. If at 1 bar pressure the gas occupies 2.27 L volume, upto what volume can the balloon be expanded?

Answer 1

According to Boyle's law,

P₁V₁ = P₂V₂

Given P₁ = 1 bar, V₁ = 2.27 L

P₂ = 0.2 bar, V₂ =?

\(\therefore\) 1 x 2.27 = 0.2 x V₂

V₂ = \(\frac{1\times 2.27}{0.2}\) = 11.35 L

Since balloon bursts at 0.2 bar pressure, the volume of balloon should be less then 11.35 L.
