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 $22.7$ L volume up to what volume can the balloon be expanded?

• A. $11.35$ L
• B. $22.7$ L
• C. $44.8$ L
• D. $67.3$ L

Answer 1

The correct option is A $11.35$ L

According to Boyle's law,

$P_1{V}_1=P_2{V}_2$

Here $P_1=1$ bar, $V_1=2.27$ L

$P_2=0.2$ bar

$\therefore V_2=\frac{1\times 2.27}{0.2}=11.35$ L.

Hence, the correct option is $A$.
