An autonomous underwater vehicle (AUV) operating in a lake releases a flexible gas-filled bladder from a depth of 18 metres.
The volume of the bladder at this depth is 45.0 cm3.
The pressure of the gas inside the bladder at this depth is 280 kPa.
The bladder floats to the surface of the lake without changing temperature.
Calculate the volume of the gas-filled bladder when it reaches the surface.
Atmospheric pressure = 105 kPa
