Homework Help Overview

The problem involves a spherical balloon inflated to a diameter of 60.0 cm, initially at atmospheric pressure and temperature, which is then taken 25.0 m underwater where the seawater temperature is lower. The focus is on determining the gauge pressure of the air in the balloon at this depth.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the relationship between the pressure inside the balloon and the external pressure at depth, with some questioning the assumptions regarding pressure equality. Others express a desire for hints or guidance without providing direct solutions.

Discussion Status

The discussion is ongoing, with participants sharing their thoughts and attempts. Some have offered insights into the pressure dynamics involved, while others are seeking clarification and further exploration of the concepts without reaching a consensus.

Contextual Notes

Participants note constraints such as prohibitions on providing complete solutions and the need for mathematical concepts to be discussed without revealing methods.

Homework Statement



b) A spherical balloon is inflated to a diameter of 60.0 cm. Assuming that the gas in the balloon is of atmospheric pressure (101.3 kPa) and is at a temperature of 20.0 oC.
The above balloon is then taken by a diver 25.0 m under the sea. The temperature of the seawater at this depth is 11.0 oC.
What is the gauge pressure of the air in the balloon at this depth?

Show some more attempt.Answer without method is a man without identity.

>phy81x 9uru<
 
nice logic...all i know that the pressure under the sea is equal to inside the balloon
well u got any hint?
