If water is H2O. as per science....then why not seas are on fire ?.?

Why is the sea supposed to be on fire? You might want to add some detail.\nAnd besides seawater is not purely H20. There is Sodium Chloride, which makes the sea water salty. Plus there is plenty of mineral, garbage, fecis,etc. which makes the composition of sea water to be very complex.

Okay...\n\nFor starters, water is H2O. We can make H2O by burning hydrogen gas in the presence of oxygen, easy, but then where would we get enough hydrogen gas to make even a noticeable amount of water? Besides, the problem isnt finding H2O--it's producing clean water. Most of our planet is under water, and there's tons of water vapor in the air. The difficulty is getting a large source of water where peole live, purifying it, and keeping it clean until it gets to people's homes.\n\nThe shortages in your area may be because there's just no ready source of water there, or because your community uses way too much of it. Environmental stuff like seasons play a part, too. There's usually less water in reservoirs during summer because of the decreased rainfall and increased evaporation.\n\nSometimes science isn't the problem. We already have more than enough technological remedies for every little inconvenience. Start conserving water, and you won't have to worry about shortages.

the answer is fire because if you give fire something to burn it will live, maybe even get bigger, but if you put water on it, it will go out... so the answer is... FIRE!

Everyone who has been to the beach knows that seawater is salty. Everyone also knows that fresh water in rain, rivers, and even ice is not salty. Why are some of Earth’s waters salty and others not? There are two clues that give us the answer. First, “fresh” water is not entirely free of dissolved salt. Even rainwater has traces of substances dissolved in it that were picked up during passage through the atmosphere. Much of this material that “washes out” of the atmosphere today is pollution, but there are also natural substances present.\n\nAs rainwater passes through soil and percolates through rocks, it dissolves some of the minerals, a process called weathering. This is the water we drink, and of course, we cannot taste the salt because its concentration is too low. Eventually, this water with its small load of dissolved minerals or salts reaches a stream and flows into lakes and the ocean. The annual addition of dissolved salts by rivers is only a tiny fraction of the total salt in the ocean. The dissolved salts carried by all the world’s rivers would equal the salt in the ocean in about 200 to 300 million years.\n\nA second clue to how the sea became salty is the presence of salt lakes such as the Great Salt Lake and the Dead Sea. Both are about 10 times saltier than seawater. Why are these lakes salty while most of the world’s lakes are not? Lakes are temporary storage areas for water. Rivers and streams bring water to the lakes, and other rivers carry water out of lakes. Thus, lakes are really only wide depressions in a river channel that have filled with water. Water flows in one end and out the other. \n\nThe Great Salt Lake, Dead Sea, and other salt lakes have no outlets. All the water that flows into these lakes escapes only by evaporation. When water evaporates, the dissolved salts are left behind. So a few lakes are salty because rivers carried salts to the lakes, the water in the lakes evaporated and the salts were left behind. After years and years of river inflow and evaporation, the salt content of the lake water built up to the present levels. The same process made the seas salty. Rivers carry dissolved salts to the ocean. Water evaporates from the oceans to fall again as rain and to feed the rivers, but the salts remain in the ocean. Because of the huge volume of the oceans, hundreds of millions of years of river input were required for the salt content to build to its present level. \n\nRivers are not the only source of dissolved salts. About twenty years ago, features on the crest of oceanic ridges were discovered that modified our view on how the sea became salty. These features, known as hydrothermal vents, represent places on the ocean floor where sea water that has seeped into the rocks of the oceanic crust, has become hotter, and has dissolved some of the minerals from the crust, now flows back into the ocean. With the hot water comes a large complement of dissolved minerals. Estimates of the amount of hydrothermal fluids now flowing from these vents indicate that the entire volume of the oceans could seep through the oceanic crust in about 10 million years. Thus, this process has a very important effect on salinity. The reactions between seawater and oceanic basalt, the rock of ocean crust, are not one-way, however; some of the dissolved salts react with the rock and are removed from the water.\n\nA final process that provides salts to the oceans is submarine volcanism, the eruption of volcanoes under water. This is similar to the previous process in that seawater is reacting with hot rock and dissolving some of the mineral constituents.\n\nWill the oceans continue to become saltier? Not likely. In fact the sea has had about the same salt content for many hundred of millions if not billions of years. The salt content has reached a steady state. Dissolved salts are being removed from seawater to form new minerals at the bottom of the ocean as fast as rivers and hydrothermal processes ar

u know that ice is H20 right? but that's not enough. it would easily melt if that's pure ice. so there is a Salt there. NaCl. why? because water or an ice slowly melts when thre is a substance. and vice versa when the water boils with salt.

evaporation would need to something for this to happen then where would the vapor go the chances of oceans drying up in our life times of the human race is nill if it happened the cause would have finished us long before have you any more stupid questions

Specifically, water binds to the mixture, and blocks free oxygen from reaching the material to be oxidized-its a simple smothering reaction, and is why water is effective for putting out fires.  Salt is also effective, but is reduced by the relatively large size of the particles which allows some oxygen in.  There is no specific inhibition of the oxidization reaction other than this-water is neutral to this reaction, except as a space inhibitor.

Water vapor doesn't do much to stop a fire.  Liquid water will stop a fire because there is a big gap in the amount of energy in liquid versus gaseous water.  Hence, when liquid water evaporates, it sucks up a lot of energy, and makes that energy unavailable for combustion.  It can also, I believe, work to smother the flame by keeping oxygen off the fuel source (but don't quote me on that).\n\nHowever, you must reconize that you've named elements, not molecules.  If you have those three elements in the form of water and carbon dioxide, you have nothing to burn.  If your elements are in the form of molecular oxygen and oil, then it will.  If you've got molecular oxygen, molecular hydrogen, and coal, then you bet will burn!

Water puts out ice because it covers up the fire from breathing in oxygen (which it needs).\n\nIf the water coming from the ice comes out by little tiny streams, the fire could easily evaporate that into vapor or just ignore the little stream of water.\n\nIf somehow the ice melted instantously into water and covered up the entire fire, then it could be possible.

No fire itself is not alive (it has no DNA/RNA, it does not perform metabolism, it does not reproduce via mitosis or meiosis, and it is not self sustaining), but fire is essential to life, and without the human abilty to contain and create fire - life as we know it would be quite different.

fire as in flames,in the water...

Because the salt content will dehydrate you. And severe dehydration could kill you especially if you are out at sea and medical treatment is not nearby.

Because is just a fake: chemically speaking it is impossible to oxidize water in a combustion engine in order to win energy. Water already is the product of an oxidation. Would be similar, if somebody invent a stove which is run on ash instead of wood.

i would think that the radiation from the freqs listed above should all cause excite the water molecules in the same way but to differing extents. that's a very good question; i think i'll research it.

Hydrogen and oxygen, when combined in an appropriate mixture, will burn to form water.  By itself neither pure hydrogen nor pure oxygen will burn (they need an oxidizer and a reductant respectively).  Water is a stable chemical component that does not have the volatile characteristics of the elements that make up its composition (hydrogen and oxygen).
