Question

A balloon is filled with one mole Helium at 0⁰C and 1 bar pressure. It will burst if pressure is decreased to 0.2 bar what is the maximum volume of balloon? *​

Answer 1

$\huge \boxed{ \fcolorbox{blue}{pink}{Answer}}$

From the equation P1 V1 = P2

P1 = 1 bar , P2 = 0.2 bar

V1 = 22.7 L then V2 = ?

The maximum value of balloon

V2 = P1V1/P2 = ( 1×22.7 )/0.2

= 133.5 L
