Is the statement of "dew turns to frost" correct in "dew turns to frost"? Why?

It means: Yun Sheng goes to the sky, and when it is cold, it forms rain; Dew quickly condenses into frost on a cold night.

Modern science and technology have proved that our earth absorbs heat after the sun comes out during the day and dissipates heat after the sun goes down at night. The atmosphere of the earth is hot. When scattering upwards, water vapor cools and becomes dew. When the temperature drops further at night, it becomes frost, especially in the Millennium and the first frost solar terms. However, only two sentences in ancient times explained the reasons for the natural phenomena such as clouds, rain and frost dew.

From a scientific point of view, the saying that "dew becomes frost" is not accurate. The frozen dew formed by frozen dew is hard small ice beads, and frost refers to the phenomenon of crop freezing damage caused by sudden drop of temperature. To form frost, the temperature of the ground or ground objects must drop below 0℃, and the water vapor content in the air on the ground should reach a certain level.

Therefore, there may not be frost in first frost, and there may not be frost in first frost. But if the temperature continues to drop, it is easy to frost.
