Answer:
PV/T = P'V'/T' V' = V(P/P')(T'/T) The pressure is decreasing by about 30%, so the volume would increase by about 30%, but the temperature is decreasing by about 10%, so the volume would decrease by about 10%. I would guess that the answer is somewhere between B and C. (I calculate it to be 115L)

? L = 100 L x 273 K/303 K x 1.28 atm / 1.00 atm = 115 L Its closer to B than C
? L = 100 L x 273 K/303 K x 1.28 atm / 1.00 atm = 115 L Its closer to B than C
