moister in the morning air.
Dew is water vapor which has condensed on a cold surface. We can see dew in the mornining on blades of grass and other leaves, esp. in winter. Since the capacity of air to hold water vapor (moisture) goes down with temperature, when air comes into contact with a cold surface, the local concentration of the moisture in the air goes above the limit and the excess water vapor condenses.
When we pour chilled water in a glass tumbler, we can observe water vapor condensing as fine drops on the outer surface of the glass. That is man-made dew for you!
it is also on cold drink...........................................

Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening. As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that of which it can evaporate, resulting in the formation of water droplets.
When temperatures are low enough, dew takes the form of ice; this form is called frost.
Because dew is related to the temperature of surfaces, in late summer it is formed most easily on surfaces which are not warmed by conducted heat from deep ground, such as: grass, leaves, railings, car roofs, and bridges.
Culturally dew is often associated with purity and freshness. This is evidenced by the names of certain popular beverages such as Mountain Dew.
Dew should not be confused with Guttation, which is the process by which plants release excess water from the tips of their leaves.
The amount of water vapor air can hold depends on temperature. The temperature at which air is saturated with water vapor is called the Dew Point. When surface temperature drops, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface. This process distinguishes dew from those hydrometeors (meteorological occurrences of water) which are formed directly in air cooling to its dew point (typically around condensation nuclei) such as fog or clouds. The thermodynamic principles of formation, however, are virtually the same.

a dew is a small drop(s) of water in the air . It is found in the early dawn. it some times lands up on the grass.

On a really humid day there is moisture in the air. That's why the air feels so heavy when it's hot outside. Well, when the temperature cools down at night, that moisture layers the ground (that's why the grass is wet in the morning).
