At the melting point, must the crystalline material be solid-liquid coexistence? Must the crystalline material be solid-liquid coexistent at the melting point?
Not necessarily. Solid, liquid and solid-liquid states are all possible as long as the temperature remains at the melting point
What is the physical process of a sea wave in several stages? What is the state of matter? What is the melting point and freezing point of the sea wave? Hope the prawn can answer concisely~~Xiela~~
The sea wave is a crystal. It absorbs heat in the melting process, including the process of endothermic heating in the solid state, the process of melting with constant endothermic temperature, and the process of endothermic heating in the liquid state. The process below 48°C is the solid state, and the process at 48°C is the mixture of the solid state and the liquid state. At this time, the temperature remains unchanged until the temperature continues to rise after complete melting, and the process beyond 48°C is the liquid state. This process is called melting.
The melting point equals the freezing point equals 48 degrees Celsius.

- 12. About the crystal and the melting point We all know that a crystal has a certain melting point. However, people observe that in winter, when the same person is standing on the outdoor ice in ordinary shoes, the ice does not melt, but after wearing the ice shoes, the ice at the blade can melt; a large piece of ice is supported by a bracket, and a thin iron ring is fastened. When a heavy object is hung under the ring, the ice under the iron wire melts into water, and when the iron wire falls behind, the water above can condense into ice. Can you guess one of the reasons?
