What Is Dew
You naturally assume that the dew is a symptom of a very simple in our nature. easy to understand and easy to explain, but also quite strange that many people have been misinterpretations about this dew. there are even books that write in full about this dew sundries.
since the time of Aristoteles until approximately 200 years ago, people assumed that the dew "falls" as well ad the rain. but in fact, dew does not fall at all.
the most prevalent from of dew we seem that we find on the leaves of plants, now it turns out is not dew at all. so we see that there are many misinterpretations about this dew.
so that we can understand whether this actual dew, we must first understand the things that relate to the air around us. the air it contains something moist air levels. the hot air can contain more water vapor than cold air.
when the air is exposed with a surface cold nature, some of the air that is experiencing condensation and damp air is left behind survive yourself above that surface in the form of small droplets of water. and that is what is called dew.
but temperature on the cool surface it has to degenerate until it reaches a certain threshold before the dew point it can be shaped. the fall in the temperature limit point that we call "point boundaries of dew".
for example, we fill water into a glass or metal cans are slick, won't immediately formed the dew on the surface, even if we fill the water in the container with ice water. the dew has not also be formed, except if the surface of the glass or cans that lowered the temperature in advance until it reaches a certain limit point.
How Is Dew Formed
how dew is formed in nature we are, first of all there should be hot air containing water vapor, it should surface tangent to one cold, which is why no dew formed on the surface or on the streets, which still stay hot temperature by the Sun, but dew can shape above the grass or crops which has become cold.
then why last dew us say that we have seen above the vegetation that's actually not true dew? the reason only a small fraction of the water points are visible by us it is the actual dew.
moreover, even most of it, comes from the plants itself, the water vapor that comes out through the pores in the leaves of the plant it is. it is the continuation of the process of irrigation of the plants were in complementary foliage with water supplies that are be vacuum form the roots in the ground.
that process starting from daytime, so the surface of the leaf it is able to survive up to the midday sun, the process lasted continuously until the evening.
in some places in this world people collect dew in a number of quite a lot and a large amount of nightly dew, water that they collect in a dew pond and used as a drinking water supply or supplies for livestock they obtain drinking water.
