On the bottom of a sea (depth 50 m) a bubble of methane gas is formed (diameter dbottom = 1 cm).
What is the diameter of the bubble when it reaches the sea surface? The temperature rises from 5
°C at the bottom of the sea to 25 °C on the surface. The hydrostatic pressure is given by pH = ρ g
h, where h is the height of the water column. The density, ρ, is assumed to be independent of
temperature between 5 °C and 25 °C.
I'm not really sure how to approach this..I want to use P1V1/T1 = P2V2/T2, but I don't know what to do about P2 because wouldn't h be zero?
