Its from evaporation, bernoulli got shit to do with it

Adiabatic expansion would contribute to some of the heat loss but you're right that most of it is from evaporation - compressed air cans aren't literally atmospheric air that's been compressed.
PV = nRT and I ain't got anything else to say about that.
Bernoulli didn't say that
No, but Benoît Paul Émile Clapeyron did
None of these words are in the Bible
hehe you said pivnert
Wait, is that not safe to do?
I mean you shouldn’t be holding the sprayer down no matter what. You shouldn’t be doing short bursts and moving it quickly like a spray paint can. And when it gets cold shake it a bunch and wait for it to heat up. If you can see the refrigerant coming out then it’s too cold and you need to stop.
Fuck you, I won't stop
Just be careful not to aim it at capacitors because they might clip off. Also just wait for the bottle to warm up when it gets cold, don't remember why, I just remember it says on the can
Can cause frost burn, some of the mechanical properties on the can can also change with temperature.
It's the fun part of making your own fizzy water
Bernoulli Sanders
Yeah I read theory.
You're all fuckin' nerds 
It's been a while since thermodynamics, but it's because of adiabatic expansion of the air. Basically the same thing happens when you blow, the air becomes cooler when it expands outside your mouth
