A bubble, placed 0.130 meter beneath the surface of a glass of diet Pepsi, rises to the surface. The air pressure at the top is 8.90 104 Pa. Note: this value of the pressure in this problem is the value for atmospheric pressure at the local elevation. Suppose that the density of diet Pepsi is the similar as that of fresh water. If the temperature and the number of moles of CO2 remain constant as the bubble rises, obtain the ratio of the volume of the bubble at the top to the volume of the bubble at the 0.130 meter depth below the surface of the diet Pepsi.
