Understand that the freezing point of a substance is the temperature at which it changes from liquid to solid under a given pressure.
Recognize that the problem specifies pure water under standard atmospheric pressure, which is 1 atm.
Recall that the standard freezing point of pure water at 1 atm pressure is a well-established physical constant.
Identify that this temperature is the point where water molecules arrange into a solid crystalline structure (ice).
Conclude that the freezing point of pure water under standard atmospheric pressure is 0~^\(\text{o}\)~\(\text{C}\).
