Understand that the boiling point and freezing point of pure water at 1 atm pressure are standard reference points in chemistry.
Recall that the boiling point of water is the temperature at which it changes from liquid to gas, which is 100 °C under 1 atm pressure.
Recall that the freezing point of water is the temperature at which it changes from liquid to solid, which is 0 °C under 1 atm pressure.
Note that temperatures can also be expressed in Kelvin, where the boiling point is 373 K and the freezing point is 273 K, using the conversion formula \(T(K) = T(°C) + 273.15\).
Compare the given options to these known values to identify the correct statement of boiling and freezing points of pure water at 1 atm.
