does water ever get hotter than boiling? 212 f ?

Answer 1

The 'boiling' point of water is drastically affected by pressure, the higher the pressure, the higher the boiling point.

Put a beaker of water under a bell jar and pull a vacuum. The water will 'boil' at room temp.

Answer 2

Water Boils At 212

Answer 3

It depends on what kind of water you are talking about. Adding salt or other compunds to the liquid will change its boiling point significantly. If regular old water is the liquid you are boiling, then the answer is NO, it does not get hotter than 212. If you were to record the temperature of the LIQUID water at boiling, you'll see it plateaus at 212. However, steam does get hotter than the liquid water, but the steam is now a different story...

Answer 4

yes, the pressure does add to it, but it is mostly based on salt/water ratio. For example take some tap water and some distilled water and put them on the same heat. The tap water will boil much quicker than the distilled water, but if you add some salt it will start boiling right away. So pure water can get much hottter. Also steam is basically really hot water right before the gas state.

Answer 5

Yes. 212f is the boiling point of water at sea level. The higher the pressure on the water the higher the boiling point. Water boils at 202.5f in Denver, the mile high city where the air pressure is lower. It boils at 210.9 in Detroit. (636 feet above sea level) Barometric pressure also affects the boiling point.

Answer 6

yes as what he say by controling the pressure you can increase the temperature over 212

but iam sorry to tell you that by decrease the pressure the boiling point will increase not as what he said that by increasing the pressure u will get more higher boiling point

if u have two vessel contain water - one is open and the other is covered so which one do u think it will boil first

the covered one sure cause it has more high pressure
this phenomena is using in distlation the petrolium oil in it is seconed step which is called " vacum distilation"
in this process u decrease the pressure under 1 par so u can increase the boiling point of materials and can easily separet it

so as concluision yes water can get hotter than 212 if u decrease the pressure

Answer 7

212 is the temperature at which liquid water turns from liquid to a gas *at standard pressure*.

But if you lower the pressure (like climb a tall mountain) then water boils at a lower temperature.

Furthermore, even after it turns to a gas, it's still water. It's just water in a gaseous state -- frequently called steam.

Answer 8

Water boils at 212F under normal atmospheric pressure at sea level. At higher altitude water boils at lower temperatures. In a high pressure boiler, water typically turns to steam at around 400F. In hydrothermal vents at the bottom of the Pacific Ocean, liquid water comes up out of the seabed at 800F.

Answer 9

Don t be silly people. The answer is a plain and simple no. Add salt? No longer water. Evaporate it? No longer water - it is now water VAPOR. At sea level (one atmosphere) water can never rise above 212F. Different pressures, sure. But now you re changing conditions. If you;re thinking, boil water and continue to heat it, it will remain at 212F. The excess energy introduced by continuing to heat the water escapes in the form of steam. It does NOT increase the water s temperature.

Answer 10

Yes. Also, if there is slightly higher pressure, like at the bottom of the pot, the temperature can be a little higher than 212f. Under certain conditions, water can be heated past its boiling point - this is called "superheated" water.
