Question

Two balloons A & B are taken at 300K. Maximum capacity of balloon A and balloon B are 750ml &1500ml respectively. When the balloon system is heated, which one will burst first?

• A. Inner balloon
• B. Outer balloon
• C. Both balloons simultaneously
• D. cannot be predicted

Answer 1

The correct option is A Inner balloon

For balloon A:-
By Charle’s law:-
$\frac{V_1}{T_1}=\frac{V_2}{T_2}\Rightarrow \frac{500}{300}=\frac{750}{T_2}$
$\Rightarrow T_2=750\times \frac{3}{5}=450K$
For balloon B:-
By Charles law:-
$\frac{V_1}{T_1}=\frac{V_2}{T_2}$
$\frac{1200}{300}=\frac{1500}{T_2}$
$T_2=1500\times \frac{3}{12}=375K$
Ans: Inner balloon
