If a bottle of oxygen with a pressure of 500 kPa with a volume of .30 L at 290 K has a temperature change to 370 K and the volume changed to 1.5 L because the bottle broke open and leaked into the bottles outer container, then what is the new Pressure of the oxygen? Remember the combined gas law equation. P1V1 / T1 = P2V2 / T2

a
.128 kPa
b
128 kPa
c
0 kPa
d
500 kPa Lp
