A weather balloon has a volume of 1750 L at 103 kPa. The balloon is then released to the atmosphere. What is the pressure if at
AnnyKZ [126]

Answer:

35.0 kPa

Explanation:

As pressure decreases, the volume of a gas increases at a given temperature., so since the balloon got bigger, the new pressure must be less than 103kPa

Assuming the temperature does not change, use Boyles Law

P1V1 = P2V2

(103kPa) (1750L) = P2 (5150L)

P2 = (103)(1750) / 5150
