Features of water :

  • Pure water has no smell, color or taste. In other words, it is colorless, colorless and tasteless.
  • It can occur in three states: solid, liquid and gas.
  • Its chemical formula is H2O .
  • It is incompressible , since being a liquid cannot be compressed.
  • Take the shape of the container that contains it.
  • It is a good conductor of electricity .
  • Molar volume (at 25ºC): 22.4 liters.
  • Molecular mass: 18.016 g / mol
  • Its density is 1 g / cm 3 .
  • The specific heat of water is 1 cal / g ° C .
  • It can go through four changes of state: fusion, evaporation, condensation and solidification.
  • It can be transformed into ice (solidification) when it is at a temperature of zero degrees Celsius .
  • Water boils when it reaches the temperature of 100 degrees Celsius (at sea level).
  • About three quarters of the surface of planet Earth is covered with water . Based on this aspect, our planet, seen from space, has a bluish color.
  • In the oceans, for example, there is a large amount of salt mixed with water.
  • Without this precious liquid the human being would not have developed on this planet. It should be noted that the body of the human being is almost completely formed by water (70%).
  • Water is also essential for the life of the other animals and plants of our planet.

Importance of water :

Water is very important for man. In ancient times, for example, the great civilizations developed on the banks of rivers.

The Egyptians, for example, depended on the waters of the Nile River for almost everything.

The Mesopotamian civilization also used this natural resource of the Tigre and Euphrates rivers.

Water consumption

Water is a precious asset that must be consumed rationally. Specialists believe that, in the future, water may be scarce if there is still waste.

In some regions of the world, mainly in the poorest, there is already a shortage of water.

Rationing and water treatment tips on a daily basis:

  • Do not use water to wash cars and sidewalks.
  • When brushing your teeth, turn off the tap.
  • Take shorter baths, soaping the body before turning on the shower.
  • Fix leaks in residential pipes.
  • For those who have a pool, avoid changing the water constantly.
  • Use water treatment procedures.
  • When you see water leaks in the streets, immediately contact the responsible water company or the town hall.
  • Add a good amount of clothes before placing them in the washing machine.
  • It helps fight water pollution.
  • Do not litter in rivers and streams.
  • Do not throw cooking oil in the pipe, as this product will contaminate the water. One liter of fried oil can contaminate up to one million liters of water.

Remember:  if we all save, water will not be missing.

Water distribution in the Hydrosphere

Oceans:  97.2%

Glaciers and ice caps:  2.15%

Water present in the subsoil:  0.62% (approximately)

Surface waters (rivers, lakes, biomass):  0.029% (approximately)

Water present in the atmosphere:  0.001% (approximately)
