Assume that none of the gas escapes from the balloon. o Previous (8 up s vurw ica tion Check Answer 0 Next E

Explanation / Answer

1.Applying Charle's law,

V1/T1=V2/T2

V1=1.15×106l

T1=11C

V2=?

T2=131C

1.15×106/11=V2/131

V2=13.69×106L

2.Applying Gay-Lussac's law,

P1/T1=P2/T2

P1=0.987atm

T1=67°C

P2=?

T2=45°C

0.987/67 =P2/45

P2=0.663atm

3.Using the combined gas law,

P1V1/T1 = P2V2/T2

3.20 × 1.40/12.20 =0.988×V/24

V2=8.92L

4.using the ideal gas equation,

PV =nRT

P=4.41atm

V=41.45l

R=0.08206Latmmol-1K-1

n=8.68mole

T=?

T=PV/nR

T=4.41×41.45/8.68×0.08206

T=256.63K

Tin Celsius=-16.37°C
