This is a natural occurring reaction from your body telling it to get ready to either fight or run away. The blood doesn't actually boil though. The pupils as well as the veins in your face dialate and this is probably why the cheeks appear more red. Adrenaline plays a big part in this.
Probably sometimes when you are presenting projects or something in front of a lot of people. That's when people get embarrassed.
It doesn't...that's a myth. Blood doesn't boil in space.
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.
it's a physical change!

No, blood does not boil in the human body. The normal body temperature is around 98.6°F, which is below the boiling point of blood. If blood were to reach the boiling point, it would result in serious tissue damage and likely death.
No, the heat on the Moon is not sufficient to boil human blood instantly. The average temperature on the Moon ranges from about 100°C during the day to -173°C at night, which is not enough to boil human blood.
No, boiling plastic can release harmful chemicals and fumes that can be dangerous to your health. It is not safe to boil plastic.
Salt changes the molecular composition of the water, causing its boiling point to go up. That's why it takes it longer to boil.
if you bring it to a full rolling boil it should be perfectly fine.
If an astronaut is subjected to extremely low pressures, such as in outer space without a spacesuit, the blood may start to boil due to the lack of atmospheric pressure. This can lead to gas bubbles forming in the bloodstream, potentially causing serious harm to the astronaut's circulatory system and vital organs. Immediate medical attention would be needed to prevent serious injury or death.
