# Gauge presssure

## 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?

## The Attempt at a Solution

101300* 25??

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?
