Initial
conditions:
Pressure P1 = 1.05 atm
Volume V1 = 27.5 L
Temperature T1 = 25 oC = 25 + 273 K = 298 K
Final
conditions:
Pressure P2 = 2 atm
Volume V2 = ? L
Temperature T2 = -40 oC = -40+ 273 K = 233 K
We knaow that P1V1/T1 = P2V2/T2
                     Â
V2 = (P1V1/T1) (T2/P2)
                         Â
= ( 1.05 atm x 27.5 L/ 298 K ) ( 233 K/ 2 atm)
                        Â
= 11.28 L
                   Â
V2 = 11.28 L
Therefore,
new volume of the gas = 11.28
