Question

as a carbonated drink, such as soda, is heated, what happens to the solubility of carbon dioxide gas in the drink?

a. it increases

b. it decreases

c. it is not affected

d. it can increase or decrease

Explanation:

The solubility of gases in liquids generally decreases with increasing temperature. When a carbonated drink like soda is heated, the temperature of the liquid (the drink) increases. According to the principle of gas solubility in liquids (Henry's law and general solubility trends for gases), as temperature rises, the solubility of a gas (like carbon dioxide) in the liquid solvent (the drink) decreases. So heating the soda will cause the solubility of carbon dioxide gas in it to decrease.

Answer:

B. It decreases
