Because that is the temperature at which water boils at the atmospheric pressure at sea level, which is 1 atmosphere. It is the maximum boiling point possible for water unless it is placed under pressure.

Why boiling in hill stations take less time?
The higher the altitude the lower the atmospheric pressure therefor water will boil faster. That is why water will not boil in the pressurised cooling system of your vehicle. The 15 lbs of pressure in the system raises the boiling point of the water to 260 degrees from 210 degrees. Take the pressure away by removing the cap and it will immediately boil over. The opposite is true when you reduce atmospherisc pressure. The boiling point of water will lower and there boil earlier.
What does water become as its is heated in an open pan?
When it is heated to over 100 degrees simply turns into vapour (steam), the reason we put lids on water to boil it is so it doesn't loose its own heat.
What is methane at 1000 degrees?
0 becuase it cant go over its boling point
Why does water with salt boil faster then pure water?
The salt alters the boiling point of the water so that it is lower, hence the faster boiling time. Actually, the addition of salt to water elevates its boiling point. This can be proven by a simple experiment. Boil water in a pot on the stove. Just as the water is starting to boil add copious amounts of salt. You should find that the water ceases to boil. If the water were to commence to boil more vigorously then this would confirm that the boiling point is depressed. The reason for the elevated boiling point is that the addition of salt (a polar compound) creates and additional bond between itself and the (polar) water molecules. This bond represents additional energy that must now be over-come to make the water boil.
What is waters reaction to heat?
Water has three states Solid (ice) liquid (water) gas (steam) When water is heated it expands and when it is cooled it contracts until about 4 degrees Celsius when it begins to expand again. So the answer to your question is it depends on what temperature the water is. If it is a liquid and over 4 degrees then it will expand. If it is not frozen but somewhere between 0 and 4 degrees it will contract until about 4 degrees and then expand. Under 0 degrees it is ice not water, over 100 degrees it is steam not water.
Why doesn't the water in your body boil when you have a high fever?
Water boils at 100 degrees not at slightly over 37.5 degrees
What temp does a kettle need to be to cause evaporation?
the temperature that is needed to boil water is 100 degrees Celsius or over.

Why do you add antifreeze to the coolant?
coolant is a mixture of antifreeze and water (usually 50/50) If you were to use just water, you would not have either freeze protection or overheat protection. Water freezes at 32 degrees. Antifreeze could protect engine to -20 to -30 degrees. Water (with no pressure) will boil at 212 degrees. Antifreeze will delay "boil-over" to a much higher temperature (I am not sure of number)
What is the temperature of boiling water in Arlington Texas?
Can be any high temp but must be over 212 to boil.
Does more salt make water boil faster?
Short answer: no, it actually makes it boil slower. Dissolving salt to water lowers its melting point and raises its boiling point by an amount proportionate to moles of salt over kilograms of water. Adding 1.00 pound of salt to 1.00 kg of water raises its boiling point by 7.95 degrees C or 14.3 degrees F
When you boil milk you have to be very careful to ensure that it does not boil over and spill on the burner There is no such problem when you boil water Why?
Milk contains proteins, which burn. Water doesn't.
How can water be made to boil at 105 degrees Celsius instead of 100 degrees Celsius?
Water could be made to boil at 105 degrees C instead of 100 degrees C by adding a solute to the water. You can also raise the boiling point of water by moving to a higher elevation or putting it under higher pressure.

When will water boil over 100 degrees celsius?
If the ambient pressure is increased, then the boiling point temperature will rise. This is how pressure cookers operate. There are many phase diagrams for water available online. Unfortunately, link posting is not available in wikianswers at this time.
How could you prove to someone that you dissolved baking soda in their water?
Boil the water and the baking soda will be left over from the evaporated water.
