SUMMARY
The discussion focuses on calculating the volume of a bubble that rises from the bottom of a 40 m deep lake, initially having a volume of 1.00 cm³ at a temperature of 10°C. As the bubble ascends to the surface where the temperature is 31°C, the combined gas law must be applied to account for changes in both temperature and pressure. The pressure at the bottom of the lake is influenced by the water column, with 1 atm corresponding to 10 m of water, necessitating the inclusion of atmospheric pressure in the calculations. The final volume of the bubble just before it breaks the surface can be determined using these principles.
PREREQUISITES
