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


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?
