Question

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

• A. 10.35L
• B. 11.35L
• C. 12.35L
• D. 1.35L

Answer 1

The correct option is B

11.35L

As the pressure and volume -$P_1$,$P_2$,$V_1$ is given only $V_2$ is to be calculated.

As temperature remains constant at room temperature, applying Boyle's law $P_1$ $V_1$ = $P_2$ $V_2$ the value of $V_2$ can be calculated.

$V_2$ =11.35L

Thus, the balloon can be expanded upto11.35L. Beyond this volume, it will burst.
