Answer 2

Answer:The balloon can be expanded up-to 11.35 L.

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.
