Answer:
The pressure is doubled, 4.0atm
Explanation:
Based on Boyle's law, the pressure of a gas is inversely proportional to its volume at constant temperature. The equation that describes this law is:
P1V1 = P2V2
Where P is pressure and V volume at 1, initial state and 2, final state of the gas.
Computing the values of the problem:
P1 = 2.0atm
V1 = 3.0L
P2 = ?
V2 = 3.0L / 2 = 1.5L
Replacing:
2.0atm*3.0L = P2*1.5L
6.0atmL / 1.5L = P2
4.0atm = P2
The pressure is doubled, 4.0atm
