A methane bubble starts at the bottom of a lake (15.0 meters down) where the water temperature is 4.00C and rises to the surface where the water temperature is 22.0C (hey, it’s summer at Rock Lake, and this is a reasonable temperature.) and the air pressure is 0.920 atmospheres. Assuming the gas is ideal and rises slowly enough that its temperature changes exactly as the water does, find the factor by which the final volume is different than the initial.
