Bromine is a liquid at 100 degrees Celsius (212 degrees Fahrenheit).

Here's why:

* Boiling point: Bromine has a boiling point of 58.8 degrees Celsius (137.8 degrees Fahrenheit).

* Melting point: Bromine has a melting point of -7.2 degrees Celsius (19 degrees Fahrenheit).

Since 100 degrees Celsius is above the boiling point of bromine, it will be in its gaseous state.
