A balloon is filled with one mole of helium at `0^@C` and 1 bar pressure. It will burst if pressure is decreased to 0.2 bar. What is the maximum volume of balloon?

Explanation

At `0^@ C` and 1 bar, GMV = 22.7L
Boyle.s law is given as, `P_1 V_1 = P_2 V_2 `
`P_1 = 1"bar " V_1 = 22.7L`
`P_2 = 0.2 " bar " V_2 =?`
The maximum volume of balloon =
`V_2 =(P_1 V_1 )/(P_2 ) = ( 1 x 22.7 )/( 0.2 ) = 113.54 L`
