Answer:
6atm
Step-by-step explanation:
Using Boyle's law equation as follows;
P1V1 = P2V2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (L)
V2 = final volume (L)
Based on the information provided in this question;
P1 = 2 atm
P2 = ?
V1 = 3L
V2 = 1L
Using P1V1 = P2V2
2 × 3 = P2× 1
6 = P2
P2 = 6atm
The new pressure of the balloon is 6 atm.
