Homework Help Overview

The problem involves an air bubble released from a submarine at a depth of 115 m in a lake, with an initial volume of 1.50 cm³. The discussion centers on determining the volume of the bubble as it ascends to the surface, considering the effects of pressure changes due to depth.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • The original poster attempts to understand how the depth affects pressure and seeks to calculate the pressure at that depth. Some participants mention Boyle's Law and discuss the relationship between pressure and volume, questioning the values for pressures at different depths.

Discussion Status

The discussion is ongoing, with participants exploring the implications of pressure changes on the bubble's volume. Some guidance has been offered regarding the application of Boyle's Law, but there is no explicit consensus on the calculations or assumptions being made.

Contextual Notes

Participants are considering the effects of pressure changes due to depth, with references to relevant physical principles like Boyle's Law and the hydrostatic pressure equation. There is an acknowledgment of the need to account for the pressure increment due to the water column above the bubble.

An air bubble has a volume of 1.50 cm3 when it is released by a submarine 115 m below the surface of a lake. What is the volume of the bubble when it reaches the surface? Assume that the temperature and the number of air molecules in the bubble remains constant during its ascent.

I'm guessing that the depth of the bubble effects the pressure (that being p1) and then the pressure at the surface is one atm? How can I calculate the pressure based on its depth?

Thanks in advance for any hints??

so p1v1=p2v2? i figured out p1 to be 12.4 atm based on the 115 m depth. would p2 be 1 atm?
 
uhm remember the pressure at the bottom has an increment of row g h i think... been a while since i last did this, but just look into that ;-p
