How long can a man survive in an airtight room that has a volume of ? Assume that his surface area is 1.70m^2.
Vol=27m^3
SA=1.70 m^3
(27M^3)(0.2094E10) =
5653.8 liters O2
= (4.83cal)(5653.8 liters O2)
(1.7m^2)(35cal/M^3*liters) =
= 59.5 cal/hr
(27307.854 cal/M^2 ) / (59.5 Cal/air)=
= 458.95 Hr

∙ 11y agoyou can survive unscathed in a vacuum for only a few seconds, after which, your blood will begin to boil, not because it heats up, but because the boiling point is reduced.. so you brain would be destroyed within 20 seconds... leave aside the exploding eyeballs, the instant emptying of the digestive system, etc.
If you were to be brought out of the vacuum, your ear drums would explode.... strangely, your ears will take care of themselves in he DECREASING pressure, but applying full atmospheric pressure, almost instantly (fast enough for you to be brought out of blood boiling danger) would cause them to explode..inwards! (in the same way that divers have to equalise their ear pressure on the way down, by pinching their nose and 'swallowing' at the same time as trying to 'blow' out of their ears.
I suggest you don't try it.... and if you become an astronaut, that you keep the door shut unless you have a space suit on.
