This temperature is called the boiling point. Once the liquid starts to boil, the temperature remains constant until all of the liquid has been converted to a gas. My compound galena’s boiling point is 1.150 grade Celsius.

This factor was good for the Egyptians as this was a potential leading cause for diseases.
