Answer:
The answer is 5 mL
Explanation:
In order to find the new volume we use the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have
[tex]V_2 = \frac{10 \times 2}{4} = \frac{20}{4} \\ [/tex]
We have the final answer as
5 mL
Hope this helps you
