- 1) With respect to blood boiling
-
- No. Body temperature is 37 C. At this temperature, the vapor
- pressure of water is about 47 mm Hg. Typical minimum blood pressure is
- higher than this.
-
- 2) With repsect to lungs freezing
-
- No, on the short term. Surface liquid/mucous in the lungs would
- evaporate, cooling the tissue as it does. The surface layer however is
- constantly warmed by the tissue not at the surface, and while it gets cold it
- won't immediately freeze. This is why your face does not freeze when you go
- skiing.
