The bond formed is intermediate between a fully ionic bond and a purely covalent bond. In rural areas, the supply of drinking water is hopelessly inadequate.
It is very significant that ice expands and floats on water because if lakes and streams froze from the bottom to the top, aquatic life would not even exist, and climate and weather patterns would be altered drastically. This special bond is responsible for most of the unusual properties of water: A comparison of boiling and Water essay in urdu points Water essay in urdu be seen in the following chart.
The absorption of huge amounts of solar heat energy by water during the day and the slow release of heat energy during the night is responsible for the moderate climate in the coastal areas.
This results in a concentration of negative charges nearer the oxygen atom and thus further from the positively charges protons that make the nuclei of the hydrogen atoms.
For a brief review of chemical bonding see appendix B. To understand why these properties exist in water and why they are essential to life on earth it is important to look at the shape and bonding patterns of the molecule because the uniqueness of water is a direct result of its shape and bonding patterns.
The versitility of water as a solvent allows it to serve as the medium of transport for so many materials. Actual measurement of the bond angle in water is By Samar Choudhury Water Introduction: A wider range of temperatures typically exist inland away from bodies of water.
We see examples of this all the time. February 2nd, admin Would you like to see more essays? The force of attraction between these polar molecules is not as strong as a covalent or ionic bond but strong enough to be significant.
Instead they must share a pair of electrons between them forming a covalent bond. Water has a number of unique and unusual properties that are responsible for its important roles it plays in the biosphere. This property combines with the MPIBP property to create the water cycle which supports life on earth.
There are almost no doubts concerning the fact that life has first appeared in water and existed in water for billions of years before finally entering the land. Individually, the high heat capacity buffers organisms from sudden extreme shifts in temperature which would be harmful to it.
These differences influence the weather globally. Without water and its unique and unusual properties, life as we know it on earth would not exist. All other substances the solid form is denser than the liquid form.
Let us look more closely at the bonding patterns of water. It provides the medium in which most biochemical interactions occur.
Clearly life cannot exist without the amazing properties of water. This property is also exploited by many living organisms. By proceeding you agree to receive promo emails form us. Many of the unique properties in the take for granted include the three physical phases, transparency, universal solvents, density behavior and temperature, high specific heat, high heat of vaporization, viscosity, surface tension and low compressibility.
The hydrogen atom is attracted to the oxygen atom of the adjacent water molecule. This is important because if water behaved like all other substances, water bodies would freeze from the bottom up and in most cases would never thaw completely during summer.
Conclusion All of these unusual properties stem from the unusual structure and bonding patterns of the water molecule.
Although this conclusion may be considered a bit far-fetched, the majority of scientists agree that life is only possible on the planets with liquid water; as a result, any planet that has even a possibility of having liquid water on its surface is studied with utmost attention, for it is considered a potential home for extraterrestrial life.
The liquid is restrained from flowing by this inward force. This is known as the clumping effect like the high melting point and boiling point the clumping effect occurs in liquid, that have hydrogen bonding.
Example Essays Introduction Water is an essential ingredient for the existence of life as we know it. It is the mutual attraction of water molecules that accounts for the ability of water to remain liquid over a broad range of temperature 0oCoC and also for its high heat of vaporization and high heat capacity.
This property is of important significance to animals in regulating body temperature because of the large amount of body heat that is required to evaporate water sweat. If not for the vast oceans on earth tempering the climate life would not exist. Other molecules, as small as water eg CO2change from liquid to gas at temperatures far below that of water.Water Pollution Eassay In Urdu Search.
