Can you boil water with boiling water?

Answer 1

No. You cant heat body A to the temperature of body B just by putting them in contact. They would end up being at some intermediate temperature. When something is boiling that means that its temperature is exactly that of the boiling point, no more, no less, so if both liquids have the same boiling point, the answer is no.

Salty water has a different boiling point than fresh water.

Answer 2

Sure! Just put it in a closed container, suck out some of the air to lower the boiling point, seal the container with the reduced pressure inside, and drop the container in the boiling water. This is Plan A.

Plan B:

Try using your mom's double boiler (a pot inside a pot) with water in both the top pot and the bottom pot, into which the top pot is inserted. Turn up the heat and see what happens.

It may take awhile for the contents of the top pot to reach the same temperature (boiling water temperature) as the contents of the bottom pot, but eventually it should happen. If it does, then you have two pots of water boiling, with the second (top) pot boiling from heat transferred from the water boiling in the first (bottom) pot.

If the experiment didn't work, go back to Plan A above.

Answer 3

One answer is given by Bekki B.
The other answer is also yes, but different method.
the boiling point of water depends on pressure.
so, immerse a container of water in the boiling water. Then you pull vacuum in this container. The water will boil. In fact you can boil water even without heating, at room temperature.
Next another way.

Put the jar of water on a pressure cooker. The pressure inside the pressure cooker will increase the boiling point of water beyond 100 degrees. You can boil water on this surface.

3. Put salt in the boiling water. It will increase the boiling point of the water. Put a jar of pure water in it. It will boil.

Answer 4

The steam from boiling water is used to make cappuccino coffee etc.
Steam has a much higher heat capacity than the water. (Latent Heat = 840 cal/g).
When steam is passed into water, it condenses, (giving up 540cal/g), as Specific Heat to the cooler water(1 cal/g/°C).
The water will boil quite quickly.
So, Yes, you can boil water with boiling water.

(Sorry Becki, you cannot superheat water at atmospheric pressure).

Answer 5

You can if you superheat the water.

This is dangerous, so kids, DON'T DO THIS.

Don't take a very smooth glass dish.
Don't put it into the microwave until it boils
Don't let it cool
Don't reheat it to just above boiling temp so that now there aren't any little air bubbles to precipitate the boiling, so you have superheated water
Whatever you do, DO NOT then take it out and throw salt in it.

I'm serious, don't even consider it.

Answer 6

Depends.

Can you raise the temperature of water to it's boiling point by adding more water that is already at it's boiling point?

No.


Can you cause part of some water to evaporate by adding more water that is already at it's boiling point?

Yes.


Can you cause water to boil if you find a way to add water that is at it's boiling point and is at a higher pressure? (And so the boiling point is higher.)

Yes.

Answer 7

actually sound played loud enough couold theoretically boil water. u would have to point your sub woofers directly over the pot and play it as loud as possible. eventually the water would start to boil.

Answer 8

I think you already are.

Answer 9

No., you can't.
