We can set up the equation as P1V1 = P2V2 and plug in the given values to solve for P2. We know that P1 = 3 psi and V1 = 2 L. We can solve for V2 by using the inverse proportionality: P1V1 = P2V2 becomes V2 = (P1V1)/P2. Plugging in the values and solving for V2, we get V2 = (3 psi x 2 L)/1.5 = 4 psi*L/3. Now we can plug in P2 = 4 psi*L/3 divided by the given volume of 3 L to get P2 = 4/9 psi. Rounding to the nearest whole number, we get 1 psi. Therefore, the answer is B) 1 psi.
