Water is essential for life water is the most important substance in our evolution and our daily lives. It's important to understand and examine the water molecule in order to ascertain how it brought about earth's thriving ecosystem and how important it is for us today. Water is a strong solvent, it's a very unique molecule that can breaks and reforms constantly. The oxygen atom also called the apex of the water molecule bears a slight electronegative charge while hydrogen possesses a more positive one kirk 225. When an oxygen atom is linked to a molecule's hydrogen atom, a bond called a hydrogen bond is formed kirk 256. There are several types of water molecule such as liquid water, ice and water vapor. In a liquid form of water it has no such spaces because hydrogen bonds constantly breaks and reforms.

Thus ice is stable hydrogen bonds that bonded together, it's less dense and will float on liquid water. If it's not this reason, the great bodies of water would freeze from the bottom up without the insulation of a top layer of ice, and all life in the water would all die bio notes water is a very small molecule that has its own unique properties therefore it behaves like a larger one. The bonds between water molecules are the covalent bonds these bonds are so strong that water resists changes in its state. Thus water has a higher melting point and a higher boiling point than any other molecule of similar size kirk 256.

When heat is applied to solid water, some hydrogen bonds get so much kinetic energy that they break and the ice melts.

Best answer जल कि जीवन के सभी ज्ञात रूपों के अस्तित्व के लिए आवश्यक है एक आम रासायनिक पदार्थ है.

Amrita hazra ,meritnation expert added an answer answered on 11/7/13 here are a few points for your reference: life without water would fail to exist as they are complimentary to each other water fulfills most of the basic activities of our lives such as brushing our teeth, drinking water, taking a bath, having our morning tea, etc. Judicious usage is required and pollution needs to be prevented for a safe future generation to exist the irregular black shapes in this cassini radar image of titan rsquo s northern polar region are believed to be liquid methane ethane lakes. Credit: nasa/jpl/usgs new discoveries have a way of messing with old definitions.

The standard definition of a ldquo habitable world rdquo is a world with liquid water at its surface the ldquo habitable zone rdquo around a star is defined as that goldilocks region ndash not too hot, not too cold where a watery planet or moon can exist. Saturn rsquo s giant moon titan lies about as far from the standard definition of habitable as one can get. The temperature at its surface hovers around 94 degrees kelvin minus 179 c, or minus 290 f. And yet many scientists now believe life may have found a way to take hold on titan.

In the past few years, instruments on nasa rsquo s cassini spacecraft and images captured by esa rsquo s huygens probe have revealed an astonishing world with a complete liquid cycle, much like the hydrologic cycle on earth, but based on methane and ethane rather than on water. Ldquo what cassini actually found on titan, from 2004 onwards, was a methane ethane cycle that very much echoes the kind of hydrologic cycle we see on the earth, rdquo says jonathan lunine, currently at the university of rome tor vergata while on leave from the university of arizona. Cassini has revealed rivers and lakes of methane ethane, the lakes evaporating to form clouds, the clouds raining hydrocarbons back down onto the surface, flowing through rivers and collecting in lakes. It is the only world in our solar system other than earth where a liquid cycle like this takes place.

But hydrocarbons are versatile: they can assemble themselves into fantastically complex structures. So one has to wonder: has hydrocarbon chemistry on titan crossed the threshold from inanimate matter to some form of life? one thing is for certain: if there is life on titan, it is not life as we know it. There is no way that terrestrial life could have originated or could survive on titan.

Ldquo dna and rna, rdquo says lunine, ldquo form out of compounds that require oxygen and phosphorus, and there rsquo s very little oxygen in the titan system. Rdquo so life on titan ldquo would have to find other molecules that carry information. Rdquo moreover, because titan is so cold, the amount of energy available for building complex biochemical structures is limited. Ldquo we don rsquo t have a lot of experience with the chemistry that might go on at these temperatures.
