Is the fog formed by liquefaction? How is it formed? What is the difference between the formation of dew and the formation of dew?

Fog is formed by liquefaction.

Specifically, it is formed by the liquefaction of water vapor in the air when the weather is cold.

Water vapor in the air liquefies to form water droplets, which attach to dust in the air to form fog.

When water drops attach to grass and other objects, it is dew.
