Dew drops on leaf

Dew is a water in the form of droplets on a thin objects dua to the condensation process.Dew drop are very beautiful.The surface are cool by radiation by heat atmosphere the rate is grater by the water drop on surfaces it's a evporates.
When temperature are low then drop change into ice: it's called frost.
Dews are not confused by guttatioon because the plants are left the excess water from tips of leaves.

Formation....

The water vapour are depends on the temperature.The temperature at which droplets form is called dew points. When the surface temperature are reached on dew points .When the atmosphere conduct the small dew drops on the surface.
The process distanguishes dew from hydrometeors which directly air cooled due to fog or clouds.
The thermodynamics process to same here. Dew are formed at night usually..

occurance

The adequate cooling the surface when take place the infrared radiation looes more energy.it received by solar energy by sun then especially case in clear night.
