Many organisms cannot survive when water reaches its boiling point of 212 o Fahrenheit. In fact, if the temperature of the water is above 160 o Fahrenheit, any organism in the water will not survive longer than thirty minutes.
Furthermore, how long can humans be in water? An untrained human can hold their breath for 4 minutes. Then after that it takes about 70 seconds to drown. It takes less time if the gasp nerve at the back of your neck is triggered.

What happens when blood is boiled?
