Question
Hi please help:
a bubble with original volume 2.5 cm^3 rises from the bottom of a lake to the surface where it grows to a volume of 5.9cm^3 at a pressure of 1.0 atm. Gas molecules were absorbed by the water as the bubble rose so that only 82% of the original gas is in the 5.9 cm^3 bubble at the surface. The temperature at the bottom is 8.2 degrees Celsius and the temperature at the surface is 23.4 degrees Celsius.
Find the pressure at the bottom of the lake (in atm). Use 3 significant figures
