Dissolved gasses can be forced out of water by boiling and cooling it. High temperatures will cause solubility of gasses to drop until they are pushed out of the water. The gases forced out usually contain nitrogen and oxygen, which would otherwise cause issues when working with oxygen-sensitive reagents.
