It doesn't...that's a myth. Blood doesn't boil in space.
Your blood would immediately boil killing you instantly.
When you go outside in outer space, you are unable to breathe. You would most likely pass out and your blood would then boil and finally freeze because of the vacuum of space.
If you are naked in space your blood will boil, you can't breath so you suffocate, you burn, you freeze and you are inflated like a balloon, in simple terms, you die.
if a human is on the moon, without a pressurized space suit, a 28 degrees Celsius temperature would definitely boil and explode the body, because there is no environment pressure.
It is possible to travel into space without a space suit, but if the capsule lost pressure, the astronauts blood would boil and they would be dead in about a minute.
yes
There is no atomosphere or atmospheric pressure. Without atomspheric pressure the astronauts blood would boil.
Extremely hot, but would feel cold if you were exposed, you would then die a sudden painful death as your blood and body suddenly boil.
no it vaporizes
Because blood is liquid, its boiling point is affected by pressure changes. Extremely low pressure would lower the boiling point enough that the blood would boil at a temperature less than body temperature.
They would quickly die of asphyxiation due to the lack of air and the astronauts blood would boil because there is very little pressure in space so this would lower the boiling point of your blood causing it to boil quicker at a lower temperature this would also contribute to killing the astronaut.
so you could breathe cause if u didnt u would die but u would also kneed a space siut so ur blood dosent boil or other stuff
