## 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?
