An underwater diver uses breathing apparatus at a depth where the pressure is 1.60 × 105 Pa. A bubble of gas breathed out by the diver has a volume of 15 cm3 when it is released. The bubble moves upwards to the surface of the water. At the surface of the water, the atmospheric pressure is 1.00 × 105 Pa. The temperature of the water is the same at all depths. What is the volume of this bubble when it reaches the surface?
