A sample of carbon dioxide gas at 292 K and 1.28 atm occupies a volume of 4.61 L. If the gas is allowed to expand to a larger volume, while at the same time it is cooled to a lower temperature, the final gas pressure could be higher or lower than 1.28 atm depending on the final volume and temperature. O will be higher than 1.28 atm. O will be lower than 1.28 atm. 9 more group attempts remaining

Explanation / Answer

P1*V1/T1 = P2*V2/T1

Here:

V2>V1

T2 < T1

so,

(V2/T1) > (V1>T1)

So,

for the equation to be valid:

P1*V1/T1 = P2*V2/T1,

P2 should be less than P1

Answer: will be lower than 1.28 atm
