A diver under water uses breathing apparatus at a depth where the pressure is 1.25 × 105Pa. A bubble of gas breathed out by the diver has a volume of 20cm3
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 × 105Pa.
The temperature of the water is the same at all depths.

Answer:
25 Cubic centimeter
Explanation:
As the pressure reduces around the gas bubble. The gas bubble will expand.
Pressure is reduced by 0.25 times (25%). Therfore, 20 cm3 + 25 % of 20cm3
= 20cm3 + 5cm3 = 20 cm3
