प्रश्न
A steel cylinder of internal volume 20 litres is filled with hydrogen at 29 atmospheric pressure. If hydrogen is used to fill a balloon at 1.25 atmospheric pressure at the same temperature, what volume will the gas occupy?

उत्तर
V = 20 litre
P = 29 atm
P1 = 1.25 atm
V1 =?
T = T1
Using the gas equation,
`"PV"/"T" = ("P"_1 "V"_1)/"T"_1`
`(29xx20)/"T" = (1.25 xx "V"_1)/"T"`
V1 = 464 litres
