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

Explanation:
At 1 bar pressure volume of the gas = V_1=2.27 L
Volume occupied by gas at 0.2 bar = V_2
P_1=1 bar,P_2=0.2 bar
According to Boyle's law;
PV = constant
P_1V_1=P_2V_2
V_2=\frac{P_1\times V_1}{P_2}=\frac{1 bar\times 2.27}{0.2 bar}=11.35 l
The balloon can be expanded up-to 11.35 L.
