Answer:
The answer is 70 kPa
Explanation:
In order to find the pressure if the volume were increased to 375 ml we use Boyle's law
That's
[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 final pressure
[tex] P_2 = \frac{P_1V_1}{V_2} \\ [/tex]
From the question
P1 = 105 kPa = 105 , 000 Pa
V1 = 250 mL
V2 = 375 mL
So we have
[tex]P_2 = \frac{105000 \times 250}{375} = \frac{26250000}{375} \\ = 70000[/tex]
We have the final answer as
70 kPa
Hope this helps you
