The melting point and the freezing point are usually the same temperature. The melting point is the temperature at which a solid turns into a liquid, while the freezing point is the temperature at which a liquid turns into a solid. The transition of matter is same. For water, it is 0 degrees Celsius. When a block of ice is heated above 0 degrees Celsius, it melts, while a glass of water is cooled below 0 degrees Celsius it freezes. There are a few substances that have different melting and freezing points. Example, agar melts at 85 degrees Celsius but freezes between 32 and 40 degrees Celsius. That is called “hysteresis,” and it’s not very common phenomenon.
