Which of the following temperatures indicates pure water melting point?

The melting point of pure water is defined as the temperature at which it transitions from solid ice to liquid water, which occurs at 0°C (32°F) under standard atmospheric pressure. This is a fundamental physical property of water that is widely accepted in chemistry.

At this specific temperature, ice crystals can form and break down as energy is added or lost, allowing water to exist in both solid and liquid states simultaneously. When examining the other temperature options, they do not represent the melting point of pure water. For example, 100°C is the boiling point of water, where it transitions from liquid to gas, while both 50°C and 32°C are not characteristic of water’s melting properties under normal conditions. Thus, 0°C is recognized as the correct temperature for the melting point of pure water.
