Question

a gas under 12 pounds per square inch pressure has a volume of 5 liters. what pressure will result in a volume of 4 l? enter your answer as a whole number, with the appropriate unit, like this: 4 psi

Explanation:

Step1: Recall Boyle's Law

$P_1V_1 = P_2V_2$ (where $P_1$ is initial pressure, $V_1$ is initial volume, $P_2$ is final pressure, $V_2$ is final volume)

Step2: Identify given values

$P_1 = 12$ psi, $V_1=5$ L, $V_2 = 4$ L

Step3: Solve for $P_2$

$P_2=\frac{P_1V_1}{V_2}=\frac{12\times5}{4}$
$P_2 = 15$ psi

Answer:

15 psi
