Why dissolving gases in the liquids is exothermic while the phase is down ? explain please

3 answers

What does "when the phase is down" mean?
I mean the phase of the gas is going towards being liquid
I'm still not sure of the question so I'll restate it as I think you are asking. Why is the phase change from vapor to liquid exothermic?
My response and I'll use water as an example:

H2O(liquid) + heat ==> H2O(gas) which clearly is an endothermic reaction. BUT if yu run the same reaction in reverse it clearly gives off heat so the reaction MUST be exothermic.
