A diver named Jacques observes a bubble of air rising from the bottom of the lake (where the absolute pressure is 50 atm) to the surface (where the pressure is 1 atm). The temperature at the bottom is 4.0°C, and the temperature at the surface is 23.0°C.
What is the ratio of the volume of the bubble as it reaches the surface (Vs) to its volume at the bottom (Vb)?
