just because water is boiling, that doesn't mean the temperature has stopped rising...
you can heat water to whatever temperature the heat source is...that is, until it is completely vaporized and if it's contained, under pressure, even hotter. assuming the poster meant 350F, are you trying to say, if my heat source is 425F, water will only be 212F. if so, I'm really sorry, but that is the most illogical thing I ever heard. by that same principal, once water has froze, 0C/32F, it cannot get any colder...say the ambient temperature is -20C/F(they're both frickin cold), but the 'ice' is only 0C/32F? not!
if I were to pour boiling water on your hand it would really burn and really hurt!
it would really scar your skin.
If I were to pour water at 500C/F(take your pick, they're both so hot, you'd never know the difference!), it would literally melt, or at the least, cook, the flesh from/on your bones.
the temperature of water can/does rise above it's boiling point.
Water canno0t be hotter than 100 C, it turns to steam once it reaches 100, and evaporates. There is no way in the world liquid water can stay liquid above 100, it is grade 4 science. 0 Ice, 1-100 water, 100+ Steam. Obviously there are variances when you change the elvevation pressure and dissolvable content of water. For a general rule, we will say we are at sea level with pur water under normal pressure conditions, similar to boiling a pot of water on the stove.
Water cannot remain a liquid past 100 Celcius, it is simple science. Water cannot stay water below 0, as it turns to ice. Once liquid water reaches 100C it turns to steam. Steam can be much hotter that 100 as it is water's gasious form.
There is 100% no chance that you can make liquid water hotter than 100 unless you put it under extremely high presures. And vicve versa, you can lower the boiling point by decreasing the pressure. At Mount Everest's peak, you can boil water at 64 C.
Steam is truely invisible to our eye. What you see when you boil water is water vapor above a layer of tru steam. Once the steam touches the cooler air, the steam then reverts back to liqid water, so you get tiny droplets of liquid water forming in the air. This white cloud is not steam, but lttle water droplets. The layer of steam is only a few mm above the surface of the boiling water.
I started as a joke, then people try and fight this FACT. Water cannot get hotter than 100, it turns to steam at that point. Steam gets as hot as the environment, and ice does too, but liquid water can only be liquid from 0-100, that's it...
You mention that you can heat water until it is all evaporated, where do you think it went? It turned into steam once that water molecule reached 100. If you put water on the stove, the liquid portion of water can't rise above 100, once it does, it turn to steam, and is no longer water. That is why the water disapears from a pot of boiling water, it turns to steam, then liquifies again in the air.....
If water was able to get hotter than 100 as a liquid, why do we use it in cooling towers, to put out fires, and so on?
