Why is it that you can put your hand in an oven at 200 yet you are unable to put your hand in a pot of boiling or near boiling water?

How do you use The One Korean hand warmers It has a plastic wrap around a liquid with a metal piece in it with the Smurf logo on it?
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.
Does salt affect the boiling point of water and why?
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.
How the bombardier beetle defends itself?
they squirt out a noxious chemical that is near the boiling point of water. it is made by combining two chemicals, hydroquinone and hydrogen peroxide, which produces an exothermic reaction.
Why doesn't water get hotter than 100 degrees Celsius?
The temperature that water boils at depends on the surrounding air pressure. In order for water to boil it must overcome this pressure to enter its vapour phase aka vapour pressure. At sea level, water boils near 100 degrees celcius if it is pure water. At higher altitudes like Mount Everest, water may boil as low at 50 degrees celcius due to the low air pressure. The purity of the water may also effect the vapour pressure. Dissolved salts and impurities cause a increase in boiling point and decrease in freezing point.
What happens if you put a plant in cold water?
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.
What to feel when place palm near to boiling water?
radiation from boiling water
What do you do if their is smoke in your house from boiling water?
Don't worry if it's above the boiling water,, but if it's not near the boiling water then their's a problem.
100 degrees is the boiling point of water in Cellicel?
The temperature of boiling water near sea level is 100° Celsius.
How would the altitude and the atmospheric pressure of Johannesburg affect the boiling point of water?
The boiling point of water decrease when the altitude increase; the value at Johannesburg is near 94 0C.
What is the boiling point of brine?
salt increases the boiling point of water so it it (boils) around 110oc This may occur at a certain concentration of salt in the water. If there is a very tiny proportion of salt in the water it will boil near to 100oC As the proportion of salt increases so will the boiling point.
Why does hot tap water not boiling when you pour it in a cup?
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.

At the what mud boils and bubles and shoots into the air?
At the volcanoes and geysers, mud boils and bubbles and shoots in to the air. There are also hot springs near the geysers.
Is condensed water good for steam irons?
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.
What kind temperature should water be?
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.
Is water pressure affected by water temperature?
hardly at all hardly at all, however in a sealed container, the pressure will rise as temp goes up, and near boiling it will go sky high
What processes take place in distillation?
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.
