To identify:Whether the bubble size become larger, smaller or remains same if they rise.
Answer to Problem 40A
As the bubbles rise, the bubbles become larger in size.
Explanation of Solution
Introduction:
According to Boyle’s law, at constant temperature, the product of volume and pressure will remain constant for a given mass of gas.
The expression for Boyle’s law is,
Here,
When ascending, scuba divers must be aware of Boyle’s law. As the diver comes to surface, pressure decreases resulting in an increase in the volume of air in the diver’s lungs.The air bubbles while going upward will grow larger.When they approach the surface, there will be less pressure in comparison to surrounding water thus allowing the gas in the bubble to expand.Hence, as the bubbles rise, the bubbles become larger in size.
Conclusion:
Thus, as the bubbles rise, the bubbles become larger in size.
