WATER STATES

Human actions can deplete the supply of groundwater, causing a shortage of groundwater and consequent sinking of the ground when the liquid is withdrawn. By removing vegetation, water flows on the ground more quickly so that it has less time to absorb on the surface. This causes groundwater depletion and accelerated soil erosion.

                                 Water is a primordial substance for living things. It is part of them and they must ingest a great quantity, to satisfy the needs of their organism and to compensate the amount eliminated by the effect of the perspiration, the breathing and by the excretion of the urine and sweat.

It is also one of the most abundant substances of nature in its three states (solid, liquid, and gaseous).

WATER STATES

A) Solid: It is constituting the snowy, glaciers of the mountain ranges, sea ice floating, etc.

B) Liquid: It is the water in the liquid state, it is constituting the seas, rivers, lakes, etc. It covers 3/4 of the Earth’s surface and constitutes 70% of the human body.

C) Gaseous: The water in this state constitutes vapor and atmospheric humidity, etc.

WATER CYCLE

The warming caused by the rays of the sun in the oceans produces evaporation. Water vapor rises from the winds and rising currents of warm air. Part of the water vapor condenses and returns directly to the ocean in the form of rain. And to the earth? It precipitates in the form of rain, snow or hail.

WATER STATES

Much of this precipitation is rapidly re-evaporated by the action of the sun. Another quantity moistens the soil, where it is absorbed by the plants and returns to the air through transpiration. Another part flows over the earth’s surface as surface water in the form of streams and rivers; And another part of the rain and molten snow seeps through the ground forming the groundwater.

WATER COMPONENTS

It consists of two hydrogen atoms and one oxygen atom.

PHYSICAL AND CHEMICAL PROPERTIES OF WATER

* It is colorless, tasteless, transparent and odorless. In large masses, it presents a blue-green color.

* Its density is 1 g / cc

* It is considered the universal solvent

* It's melting point is 0 ° C and boiling point is 100 ° C.

WATER CLASSES

A. Natural or Atmospheric Water

It is the water that is in the atmosphere due to the action of the solar rays that evaporate the waters of the rivers, seas, lakes, etc. It can be condensed, as it is the case of the fog, clouds or in the form of precipitations like the rain, hail, etc.

                                                 Natural or Atmospheric Water

B. Drinking water

It is one that is suitable for drinking and must meet the following conditions:

It should be clean, colorless, odorless and pleasant to taste.

It should contain a little proportion of mineral salts (chloride, sodium sulfates, calcium, etc.).

You should dissolve the soap and cook the vegetables.

It should not contain pathogenic germs.

That is why to obtain this type of water should be carried out procedures of purification.

C. Mineral Water

They are those containing various amounts of dissolved salts; So they have a characteristic taste and healing properties.

This water comes from the sub-soil and surface to the surface forming the springs. Likewise, these springs increase their temperature receiving the name of hot springs.

D. Distilled Water

It is the chemically pure water, which is obtained by distillation of natural waters. This water is used in the laboratory, industry, medicine, etc.

Waters that are at rest, among them, we find reservoir waters, lakes, marshes, puddles, etc.

They are the waters that run through the surface of the earth, according to the flow are called rivers, streams, and streams.
