what temperature is boiling water at after sitting for a minute?

Answer 1

If it is still boiling 100C (212F)

Answer 2

If it is pure water boiling at 1 atmosphere of pressure, the temperature will be 100 degrees C for the entire duration of boiling, so long as the source of heat is present and the action of boiling occurs.

If you are asking what the temperature of the water would be if it were brought to boiling and then *removed* from the source of heat, there is too little information. Many variables must be considered, including volume of water, nature of the container, ambient temperature and pressure.

Answer 3

Boiling occurs when the vapor pressure of the substance you want to boil is equal to the atmospheric pressure.

Assuming a relatively normal pressure of 1 atmosphere (at sea level) water ordinarily boils at 100 degrees Celsius. It is possible to change the boiling temperature of water to room temperature if you lower the atmospheric pressure enough. The lower atmospheric pressure explains the approx. 95 degrees Celsius boiling temperature here in Denver, CO (at about 1 mile above sea level).

So, to answer your question, the temperature of the boiling water depends on the pressure, but if you assume that the pressure is the normal pressure encountered at sea level, the temperature of your boiling water is 100 degrees Celsius.

You may ask: But I've been heating it for an entire minute (or 10, or 30), so why isn't it a higher temperature (like 100.5 degrees)?

The reason why the temperature stays at 100 is that water that is boiling is at equilbrium between the two phases (liquid water and water vapor) and will continue to remain at its initial boiling temperature even when it is continually heated. This is because any heat energy you continue to put in while it is boiling is used to convert more liquid water to water vapor (the heat required to change a liquid in to a vapor is called the "Enthalpy of vaporization," and is usually found in units of kJ/mol).

So, if you are heating a boiling liquid and there is still liquid left, any energy you continue to put in only changes more liquid to more vapor, it doesn't raise the temperature.

So, your answer (assuming this boiling water is still being heated for that 60 second period) is 100 degrees Celsius (or slightly less at altitude).

If, however, your boiling water was sitting away from heat, and the 60 seconds was long enough to make the equilibrium between liquid water and water vapor disappear (leaving you with 100% liquid water), your uninsulated system would have naturally cooled a bit.

Because of the assumptions that need to be made but that are not explicitly stated, namely the location and condition of where the water is sitting (e.g. away from heat on top of Mt. Everest; on a burner at sea level that is still supplying it with enough energy to preserve the equilbrium state of boiling), this is a poorly phrased question.

Answer 4

At room temperature and pressure 1 minute will not make big difference, but of course the temperature will go down 10-20 degrees C.

Answer 5

You're question is impossible to answer, due to a lack of data. You'd need to know the air pressure on the water, room temperature, if it's pure H2O, and whither it just reached 100 C (212 F) before you took it off its heat source.

Answer 6

It depends on how much heat/energy is being put into it during that minute. There are tons of factors involved, like pressure, outside temperature, how much heat is continually being put into it, and stuff like that.

Answer 7

ninety degrees celsius
