1. The problem statement, all variables and given/known data 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? 2. Relevant equations 3. The attempt at a solution 101300* 25??
