Pressure and Volume are related by Boyle's Law as:
[tex] P_{1}V_{1} = P_{2}V_{2} [/tex]
P1 = Initial pressure = 1.25 atm
V1 = Initial volume = 2.50 L
P2 = Pressure at ocean bottom = 95 atm
V2 = Volume at ocean bottom = x = ?
Using the values in the equation, we get
[tex]1.25(2.5)=95x \\ \\
x=0.03 L
[/tex]
This means, the volume at the bottom of the ocean will be 0.03 L. The volume is decreased due to increased pressure.
