Normal boiling point of CO2
« on: October 25, 2008, 01:09:02 PM »
What is "the normal boiling point of CO2"?

At 1 atm, CO2 goes from solid to a gas. Is this considered boiling? Isn't this subliming?

Doesn't exist. At 1 atm CO2 sublimes.

OK that's what I thought, but some people, Wikipedia, and some other sites label that sublimation point as its "boiling point".

Not exactly. They list sublimation in the "boiling point" data field, to not left it empty, but they put in parenthesis information about what it really is. That's not the same as naming "boiling" "sublimation".
