Now generally, to degas a solvent, typically water, WE BOIL it......

Explanation:

And we can represent this by the equation:

"Dissolved gas in water" +Deltararr"Degassed water"+"Gas in air"

Because we have had to supply energy to break up the solute/solvent interactions, the reaction as written is ENDOTHERMIC. It follows that the initial dissolution of the gas in the solvent was EXOTHERMIC. Does you agree?
