Water is in a gaseous state at 105 degrees Celsius (219 degrees Fahrenheit).

Here's why:

* Boiling Point: Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at standard atmospheric pressure.

* Above Boiling Point: At temperatures above its boiling point, water transitions from a liquid to a gas (water vapor).

So, at 105 degrees Celsius, water would be actively boiling and turning into steam.
