Very much so. As scuba divers, we are swimming in liquid water but can easily
freeze up a regulator when we are in water that is near freezing because of gas
expansion.
In addition, you can make it snow in the middle of summer by taking a full
scuba tank and opening it up without a regulator. The cold air will literally
freeze the moisture in the air. I'm sure there's probably a YouTube video of
that...

Is there an expansion due air (gas) temperature drop, say from a 200 bar
cylinder to a diver’s mouthpiece after the pressure regulator? Like a JP
expansion effect? Of course with scuba diving, the regulated pressure is
depth dependent, but still. Any values in °C?
