Is there a name for the opposite reaction to the dissolution?

When atmospheric $\ce{CO2}$ reacts with water to form $\ce{H2CO3}$, this is called dissolution, isn't it? What term would you use for the opposite reaction when it occurs at atmospheric pressure (e.g. due to temperature change)? For a solid it would be precipitation, but here it is for a gas.

• Good question! But it is maybe worth noting that the process of gaseous carbon dioxide dissolving in water and the reversible reaction of carbon dioxide with water to form carbonic acid are two separate processes. – iad22agp Jan 15 '15 at 21:07
