Explain why an opened bottle of carbonated water keeps its fizz longer if kept in a refrigerator than if kept at room temperature.

a. As time elapses the concentration of CO2 inside a closed refrigerator increases. The increased partial pressure of CO2 increases the solubility of CO2.

b. As time elapses the concentration of CO2 inside a closed refrigerator decreases. The decreased partial pressure of CO2 increases the solubility of CO2.

c. The solubility of gases decreases with decreasing temperature.

d. The solubility of gases increases with decreasing temperature.

Most gases are more soluble in cold than in hot (warm) water.
