It's actually a lot more complicated and inconsistent than that.
A grossly oversimplified explanation is that atmos itself doesn't change the temperature of chemical reagents but events CAUSED by atmos can affect chemicals.
Hot gasses have several events associated with them, most prominently hotspots and sparks from broken lights.
To my knowledge, there are no events associated with cold gasses.
Thus, your beer stays lukewarm, but your welding tanks still explode.
