Salt will increase the boiling point and decrease the freezing point of water due to colligative properties. Table salt (NaCl) breaks into ions when dissolved. This lowers the vapor pressure of water. When salt dissolves its ions are moving around in the water, and some are near the surface. Rather than all the water just boiling off, some of these ions get in the way, which will raise the boiling point. This effect is not only caused by salt, but by dissolved substance. In general, the more ions or particles dissolved, the greater the effect on boiling point, so MgCl2 would have a greater effect on boiling point than NaCl, because MgCl2 dissociates into three ions instead of two.
When a cold spoon is placed near the vapor of boiling water, the water vapor cools down and condenses into water droplets on the surface of the spoon. This happens because the cold temperature of the spoon causes the water vapor to lose energy and transform back into liquid form.
Slightly bend the metal until it pops (the metal, not the plastic ;) This will start the hand warmer going. The liquid will crystallize, giving off heat. When done, you can heat it in a pot of hot (near boiling) water and reuse.
The steam from a kettle will hit the cold window surface and lose heat rapidly, causing it to condense back into water droplets. This is because the cold window cools down the steam quickly, which is why you can see the steam forming water droplets on the window.
While ice cold water can shock the roots of a plant, hot water can actually be worse. Boiling or near boiling water can damage the fine roots of plants, inhibiting water take-up by the roots. Room temperature water is best, especially for watering house plants. If you have a dried-out peat based potting soil, warm (not hot) water can help the peat to re-hydrate. Hot water on foliage can also be detrimental - many leaves are sensitive to direct extreme temperatures, which is one reason that boiling water can be an effective organic herbicide to treat small weedy tasks, like grass growing in sidewalk cracks.

Don't worry if it's above the boiling water,, but if it's not near the boiling water then their's a problem.
The temperature of boiling water near sea level is 100° Celsius.
The boiling point of brine, which is a solution of salt in water, is higher than the boiling point of pure water. The exact boiling point of brine depends on the concentration of salt in the solution. For a typical concentration of around 23.3%, the boiling point of brine is around 109.4°C (229.9°F).
The boiling point of water decreases as elevation increases, so near the Dead Sea, which is below sea level, the boiling point would be slightly lower than at sea level. Therefore, the cooking time for pasta would be slightly longer near the Dead Sea compared to cooking at sea level due to the lower boiling point of water.
Water heaters are normally set to temperatures well below boiling; 140 degrees Fahrenheit is typical. Also, some heat loss occurs as the water travels through the pipes from the heater to the tap, so the water generally emerges at closer to 120 degrees, which is nowhere near boiling.
Water at 213 degrees Fahrenheit is in liquid form. At this temperature, water is near its boiling point of 212 degrees Fahrenheit, so it is very hot but has not yet reached the boiling point to turn into steam.
At the volcanoes and geysers, mud boils and bubbles and shoots in to the air. There are also hot springs near the geysers.
You would use distilled water for your iron. Distilled water is water that is recovered (condensed) overhead of a boiling source of water generally at low pressure (near atmospheric). So, they are essentially the same.
That depends for what purpose you want the water. For example: if you want to broil some tea, it's best if the water is near the boiling point. At sea level, that would be 100 degrees.

In distillation water is boiled to make steam (or heated to near boiling point to be precice) & the resulting vapour is cooled to provide a pure product, be that water or spirit.
