Which of the following statements about the solubility of gases in liquids is not correct? A warm can of soda fizzes more than a cold can of soda when opened because gases are less soluble at higher temperature. An opened can of soda goes "flat" because the partial pressure of carbon dioxide is lower in the atmosphere than in the unopened can. Fish kills may occur in the summertime because an inadequate amount of oxygen is dissolved in the water. A solution stored under an atmosphere of pure nitrogen will contain more dissolved nitrogen than the same solution stored under air because air is only 80% nitrogen. none of the above
