Answer:
8L
Step-by-step explanation:
Data obtained from the question include:
V1 (initial volume) = 12L
P1 (initial pressure) = 2atm
P2 (final pressure) = 3atm
V2 (final volume) =?
Using Boyle's law equation P1V1 = P2V2, we can obtain the final volume of the balloon as follow:
P1V1 = P2V2
2 x 12 = 3 x V2
Divide both side by 3
V2 = (2 x 12) / 3
V2 = 8L
Therefore, the volume of the balloon when the pressure is changed to 3atm is 8L
