Why is it that after boiling water for long the pot turns gray?

The mineras in the water cling to and react with the metals of the pot. Aluminum pans do this frequently.

What does water do at 212 degrees?
If you mean 212 oF then this is boiling point of water. If you mean 212 oC then the water has long evaporated into a gas.
What is temperature at which liquid turns to gas?
It's different for every gas. It also depends on the pressure. You actually need a two-dimensional depiction called a phase diagram. Check out the Wikipedia article on 'vapor'. You also need to consider that most substances will have a non-zero vapor pressure at temperatures below their boiling points and at least down to their freezing points. As long as you're not interested in some pedantic definition of gas which differentiates it from vapor, there is no specific temperature at which a gas turns to liquid, or vice versa. answ2. A gas turns into a liquid at its condensation temperature, or in the reverse direction, a liquid turns into a gas at its boiling point.
Is boiling water irreversible?
From a thermodynamics standpoint, it depends how the process is carried out. If the system (the water) and the surroundings remain close to equilibrium during the entire process then the water boils reversibly. So if the change in temperature is approximately zero throughout the process and the process takes an infinitely long amount of time to carry out you can reversibly boil water.If you were asking whether water vapor can turn back into liquid water, then yes the process of turning water into water vapor is reversible.
How long will it take to boil 5 gallons of water with propane gas?
I am actually doing that right now. I have been heating it for about 15 min but it still inst boiling yet. I will let you know when it starts boiling though.
How is vaporization and boiling different?
boiling is when you heat up water to 100oc or 212of then if you keep it long enough it will turn into water vapour since particles first vibrate a little away from each other then they get too hot then they fly there is a difference its just a matter of time for it to happen :J
When you take heat from water it turns into?
Boiling water will produce steam (water vapour). Eventually, if boiled long enough, all the water will have evaporated, with the risk of the bottom of the pan or kettle melting.
Why is Water Boiling in radiator?
The water is boiling in radiator because it's temperature(radiator's) reaches the boiling point of water when the engine works for a long time.
Do plants grow faster with tap water or grey water?
gray water, as long as slinity levels are low and no phytotoxic chemicals are added to the gray water

Why is a cocoon put in boiling water for obtaining silk?
Silkworm cocoons are placed in boiling water to make the one long continuous thread separate from it.
How long do you cook asparagus tips?
120 seconds in boiling water.
How long does it take to freeze boiling water in a freezer?
Around a day.
What are the factors that affect the boiling of liquids?
Short answer: Pressure. Long answer: Pressure changes the boiling point of a substance. The higher the pressure, the higher the boiling point, and vice versa. For example, boiling water in the mountains is easier than boiling water at sea level. Note that boiling water is not necessarily hot. You can boil water at room temperature if the pressure is low enough (For example, using a vacuum generator)

By the time water hits its boiling point the water is safe.
