What is the state of the crystal at its melting point
It may be a solid (just reaching the melting point, but unable to continue to absorb heat), a liquid (just reaching the freezing point, but unable to continue to release heat), or a solid-liquid coexistence (in the process of melting or solidification).
It may be a solid (just at the melting point, but can not continue to absorb heat), a liquid (just at the freezing point, but can not continue to release heat), or a solid-liquid coexistence (in the process of melting or solidification).
The melting point of the sea wave is 48, and the temperature is 48. What is the state of the sea wave? Solid state? Liquid? Solid-liquid coexistence? Or is it all possible?
It's all possible,
1L's answer is wrong, water at zero degrees Celsius will be solid-liquid coexistence, but if the ice just finished, the liquid could be 0 degrees Celsius, there is 0 degrees Celsius ice and 0 degrees Celsius water.
Similarly, a sea wave of 48 degrees Celsius is possible in all three states.

- 20. 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?
