question
which of the following will increase the solubility of carbon dioxide in seltzer water?
select the correct answer below:
heating it up.
storing it in a vacuum.
keeping it in the refrigerator.
keeping it outside the refrigerator.

Explanation:

Step1: Solubility of gases in liquids

The solubility of gases in liquids is affected by temperature.

Step2: Effect of temperature

As temperature increases, the solubility of gases (like carbon dioxide) in liquids decreases. Heating it up (Option A) and keeping it outside the refrigerator (Option D) increase the temperature, so they decrease solubility. Storing in a vacuum (Option B) removes the gas source, so no increase. Keeping in the refrigerator (Option C) lowers the temperature, which increases the solubility of carbon dioxide in seltzer water as per the principle that for gases in liquids, lower temperature means higher solubility.

Answer:

C. Keeping it in the refrigerator.
