Answer:
<h2>The answer is 70 kPa</h2>Explanation:
In order to find the pressure if the volume were increased to 375 ml we use Boyle's law
That's
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 final pressure
From the question
P1 = 105 kPa = 105 , 000 Pa
V1 = 250 mL
V2 = 375 mL
So we have
We have the final answer as
<h3>70 kPa</h3>Hope this helps you
