A diver dives to a depth of 40 m in fresh water where he releases a toy balloon of volume 10 cm^3. What will be the size of the balloon when it reaches the surface? (The pressure increass at a rate of 1 atmosphere for every 10 m descent in fresh water)
The Attempt at a Solution
P1= 4 atm
V1= 10 cm^3
I just dont know how to find the pressure when it reaches the surface... what would the pressure be?
