Answer:
The volume of bubble is 5.13 cm³.
Explanation:
Given that,
Volume of air bubble = 1.9 cm³
Gauge pressure = 1.7 atm
Suppose we find the volume of the bubble as it reaches the surface
We need to calculate the pressure at bottom
Pressure at bottom=gauge pressure+atmospheric pressure
[tex]P=1.7+1.0=2.7\ atm[/tex]
We need to calculate the volume of bubble
Using Boyle's law
[tex]P_{1}V_{1}=P_{2}V_{2}[/tex]
Put the value into the formula
[tex]2.7\times1.9=1.0\times V_{2}[/tex]
[tex]V_{2}=\dfrac{2.7\times1.9}{1.0}[/tex]
[tex]V_{2}=5.13\ cm^{3}[/tex]
Hence, The volume of bubble is 5.13 cm³.
