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.
212 degrees Fahrenheit
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.
Yes, you can over boil water when cooking. This occurs when the water evaporates completely, leaving the pot dry and potentially causing damage to the pot or stove. It is important to monitor the water while cooking to prevent this from happening.
No, when you boil a beaker of water over a Bunsen burner, the water will not turn into a gas. It will reach its boiling point (100°C at sea level) and turn into steam, which is the gaseous form of water.
Water (h2o) boils at 212 degrees Fahrenheit. It boils at 100 degrees Celsius This is however dependent upon atmospheric pressure. The above is true down at sea level all over the world (however minor differences can be measured contributed by high or low pressure at the time.) Very high up in the Andes mountains it is said that water boils at such a low temperature that it is even difficult to boil an egg without a pressure cooker. You can easily make an experiment regarding boiling hot water. Fill up a syringe halfway (preferably a large one) with boiling hot water. Plug the hole at the end, and pull some more to make a negative pressure inside. You will see the water starting to bubble. It boils due to the lowering of the pressure inside.
Water boils at 100 degrees not at slightly over 37.5 degrees
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)
212 degrees Fahrenheit
Can be any high temp but must be over 212 to boil.
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
Milk contains proteins, which burn. Water doesn't.
To properly boil water in a pan, fill the pan with water, place it on a stove over high heat, and wait for the water to come to a rolling boil. Once it reaches a boil, reduce the heat to maintain a gentle boil until the water is ready for use.

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.
the temperature that is needed to boil water is 100 degrees Celsius or over.
Yes it is possible. Boiling takes place when the saturated vapour pressure becomes equal to the surrounding pressure. So by reducing pressure over the surface of liquid even at 20 deg celsius it is possible to boil.
