Cold exhale?

[phantom2x]

I never noticed this before, but when I exhale after taking a puff, it's quite cold. Like if I blow a soft stream at say, my hand, it will be colder than if I blow with that same pressure of just air. Anyone else notice this?

Yep. I can sense it sometimes if I blow upward off the tip of my nose. Like a cool mist. Like it.

Evaporative cooling. Same concept as your A/C system. Compress vapor into liquid = heat, expand liquid into vapor= cool.

Evaporative cooling...when water/liquid evaporates off your skin it carries energy (heat) with it. It's one reason you perspire. More proof that "vapor" isn't smoke, it's more like what a water mister type of thing would do.

EDIT: Let's all post at once... any others?

I noticed this immediately. If I was walking when I blew the vapor out I could feel the vapor flow over my face and it definitely felt cooler than ciggy smoke.

I noticed this while blowing vapor down my shirt when my boss walked in my office mid-vape

I noticed that also...nice during this hot weather we've been having.

I'm happy I caught this thread, I just noticed it this summer with the hot weather and was wondering why it's doing that, it's quite cool, I have a portable air conditioner

That was one of the first things I noticed when I started vaping.
