Here are the temperatures at which water changes state, along with the names of the states:

* Freezing/Melting Point: 0° Celsius (32° Fahrenheit)

* Water changes from a liquid to a solid (ice) at this temperature.

* Water changes from a solid to a liquid at this temperature.

* Boiling/Condensation Point: 100° Celsius (212° Fahrenheit)

* Water changes from a liquid to a gas (water vapor) at this temperature.

* Water changes from a gas to a liquid at this temperature.

Important Notes:

* These temperatures are at standard atmospheric pressure (sea level).

* The boiling point of water can change depending on the pressure. For example, water boils at a lower temperature at higher altitudes.
