Would your breathe freeze at 40 degrees below zero?

Would your breathe freeze at 40 degrees below zero?

[NamerOfStars]

No. The air we exhale is still about 78% nitrogen, the freezing point of which is -396. Up in Edmonton during the winter, it's actually not that uncommon for the temperature to actually REACH forty below, and the air doesn't freeze.

Now, you DO eventually risk frostbite to your lungs if you breathe in too quickly when it's too cold out; I'm told that that's a serious concern up in Barrow. But that's hardly the same as breath freezing.

[JacobJordan]

Breath no. Though exposure to temperature that cold for more than a few minutes would result in severe frostbite

[Asker]

How cold does it take to breath to freeze?

[Asker]

Also what do you mean by exposure? You mean open part of body? Like naked hands?

[JacobJordan]

Exposure means skin being exposed. Your breath will never really freeze if it gets to cold to breathe you just stop being able to inhale. Though at -40 even covered you will reach frostbite and hypothermia pretty fast

[Asker]

Really? Wearing a lot of layers of clothes and socks and maybe 2 pairs of gloves doesn't prevent it from frosbite?

[JacobJordan]

Standard body temp is 98 ish degree. Anything below that externally means you lose heat naturally. -40 is almost 140 degrees below standard body temp. At 32 area you want gloves. At 0 you want good gloves. At -10 hand warmers are advised. -30+ it is highly advised you do not go outside for any reason. It may take a bit longer but unless you can safely generate heat to increase your body temp faster than it would drop yeah you going to have frostbite pretty damn quick.

[Asker]

I don't feel the need to wear gloves at minus 10-12 degree celcious, it is very comfortable temps if there isn't wind.

[Asker]

Coldest I've been out was minus 30 degree celcious, that was so terrible in terms of coldness. I don't know about the beyond.

[Asker]

About the town I had been to, somebody made a comment, even your breathe would freeze. Those are exegerations, even at -40c, it wouldn't be such a thing. Yeah.

How cold does it need for breathe to freeze? Freezing point of CO2?

[Daniela1982]

Didn't you already ask this question, except then it was 60 degrees below zero?

[Effably]

... celsius? Fahrenheit? Kelvin?

If Kelvin. Sure. You'd die instantly.
Celsius and Fahrenheit, no but you're risking injuries.

[Likes2drive]

Freeze no but you’ll see your breath and you don’t want to breathe in cold air like that, it’s quite uncomfortable

[handsomelad70]

That and the rest of you if you're aren't properly dressed for such Arctic cold.

[Asker]

Would you say frosbite would happen in 2 minutes?

[AngryCarl]

Centrigrade or Farenheit? No wait, it doesn't matter. Both.

Probably. I've never been cold enough to test it.

[Redstang88]

Yeah it doesn’t have to be that cold
