Boyle's law says that the volume of a gas varies inversely with the pressure. when the volume of a certain gas is 5l, the pressu

Mrac [35]

Boyle's law states:
pV = C, where p = pressure, V = volume, C = constant.

Therefore,
p1V1 = p2V2

And the,
p2 = p1V1/V2
p1 = 512 kPa
V1 = 5l
p2 =?
V2 = 4l

Therefore,
p2= 512*5/4 = 640 kPa
