Question

A bubble of air is underwater at temperature 15°C and the pressure 1.5 bar. If the bubble rises to the surface where the temperature is 25°C and the pressure is 1.0 bar, what will happen to the volume of the bubble?

• A. Volume will become greater by a factor of 1.6
• B. Volume will become greater by a factor of 1.1
• C. Volume will become smaller by a factor of 0.70
• D. Volume will become greater by a factor of 2.9

Hint:

When dealing with gas volume changes, use the combined gas law: \( \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \).

Answer 1

The Correct Option is A

The volume of the bubble is affected by both temperature and pressure. Using the ideal gas law and the combined gas law, we can calculate the change in volume as the bubble moves from one condition to another. The volume increases by a factor of 1.6.

Step 2: Conclusion.
The volume of the bubble becomes greater by a factor of 1.6, corresponding to option (a).
