What Is the Melting Point of Water? - ThoughtCo

The melting point and freezing point of water ideally are the same, especially if there are gas bubbles in water, but if the water is free of nucleating points, water can supercool all the way down to −42 °C (−43.6 °F, 231 K) before freezing. So, in some cases, the melting point of water is considerably higher than its freezing point.
