A salvage diver uses a manual pump to inflate a submerged lift bag.
The pump transfers 45.0 litres45.0\text{ litres}45.0 litres of air from the atmosphere, where the pressure is 100 000 Pa100\,000\text{ Pa}100000 Pa, into the lift bag.
Once the lift bag is fully inflated under water, the pressure of the air inside it is 180 000 Pa180\,000\text{ Pa}180000 Pa.
Calculate the volume of the inflated lift bag in litres.
Assume the temperature of the air inside the lift bag remains equal to the temperature of the atmospheric air.
Use the equation:
pressure×volume=constant \text{pressure} \times \text{volume} = \text{constant} pressure×volume=constant
