A baloon is filled with hydrogen at room temperature. It will burst if pressure exceeds `0.2` bar . If at 1 bar pressure the gases occupies `0.30` L volume , upto what volume can the balloon be expanded by filling `H_(2)?`

Explanation

Here `P_(1)=1 "bar" P_(2) 0.2"bar"`
`V_(1)=0.30L v_(2)=?`
From Boyle.s law equation:
`P_(1)v_(1)=P_(2)v_(2)`
`:.v_(2)=(P_(1)V_(1))/(P_(2))=(1xx0*30)/(0*2)=1*5L`
Since the baloon bursts at 0.2 bar pressure. Here the valume of ballon should remain less than `1.5L`.
