How is the amount of dissolved air in hot water compared with cold water?
Answer and explanation
Correct answer: Less
Air is a mixture of gases, including oxygen and nitrogen. The solubility of most gases in water decreases when temperature increases, because heated gas particles escape more readily from the liquid. Consequently, hot water generally contains less dissolved air than cold water. The amount is not infinite or necessarily equal at different temperatures; it depends on temperature and other conditions.
