What is the state change of dew?

Dew is formed by evaporation-liquefaction of water.

During the day, due to the irradiation of the sun, the whole surface temperature rises. At night, the sun turns to the other hemisphere, which leads to the decrease of geothermal energy and surface temperature. At this time, there is a "temperature difference" between the water vapor in the air and the ground, forming heat conduction, that is, heat will be conducted from the water vapor to the ground. In this process, water vapor releases heat, liquefies into small water droplets and adheres to plants and the ground, thus forming dew and wetting the ground.

Description of dew:

In the morning, when the first ray of sunshine shines on the earth through the sky, dew appears quietly. It is round, clear and transparent. Through it, we can see the colorful natural world. Diamond-like dew quivered everywhere on the lush grass, flashing colorful spots. On the broad lotus leaf, there are sparkling pearls, one, two, one thousand and ten thousand. Like bright stars in the night sky, like blue waves covered with precious stones, like thousands of shining eyes.
