SUMMARY
The discussion centers on calculating the depth of a water tank based on the expansion of a bubble that triples in volume as it rises. The relevant equation is the ideal gas law, represented as PV=nRT, and the relationship between pressures at different depths is established using P1V1=P2V2. The correct atmospheric pressure at the water's surface is 100 kPa, leading to the conclusion that the depth of the tank is 20 meters, not 30 meters as initially calculated. Misunderstandings regarding pressure units and the atmospheric pressure value were clarified during the discussion.
