Question

As pressure decreases so does boiling point. One reason astronauts wear space suits in space is because of the decreased pressure in space. Explain what might happen to the blood of an astronaut subjected to extremely low pressures.

Answer 1

He'll die because his blood pressure is decreasing

Answer 2

First, we need to be aware that our blood is also  a form of liquid.
So, when the astronaut is placed in within the environment that has decreased pressure,  the temperature inside the astronaut's body will definitely increase but it won't cause the boiling effect like in water (it won't even break the arteries). But it could endanger the astronaut's life because it makes the blood unable to circulate properly due to unstable blood pressure
