Difference between Melting point and Freezing point. Examples of substances having separate Melting and Freeing points.
The melting point of a substance is defined as the temperature at which a solid is turned into liquid depending on the purity of the substance.
The freezing point of a substance is defined as the temperature at which a liquid changes its state into solid.
For some substances, the melting point and the freezing point is the same.
The melting point is considered as a characteristic property of a solid and as you increase the temperature, the solid will melt. The freezing point is not because there are substances including water that can be supercooled that is cooled beyond the freezing point without the formation of solid crystals. You can cool water well below its melting point and it won't turn to ice (freeze) by cooling very pure water in a freezer in a smooth container to as low as −42 °C.
