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

Explanation

According to Boyle.s Law `p_1V_1 = p_2 V_2`
If `p_1` is 1 bar, `V_1` is 2.27L
If `p_2` = 0.2 bar, then `V_2 = p_1V_1/p_2 = V_2 = 1bar xx 2.27L/0.2bar = 11.35 L`
Since balloon bursts at 0.2 bar pressure, the volume of balloon should be lass than 11.35L
