A boat is moved from land to water by rolling it across a set of cylindrical airbags.

Figure for Question S2.3.2—Evaluating question 1 — IB Physics HL

When fully inflated, an unloaded airbag has a diameter of 1.80 m and a length of 24.0 m . At a temperature of $15^{\circ} \mathrm{C}$ , an airbag can hold 4200 mol of gas.

Identify an assumption used in this estimation.

The boat is then released to roll down across the airbags. When the boat loses contact with an airbag at the top of the slope, the airbag expands adiabatically.
