how long does it take to boil a cup of water in the microwave?

Answer 1

normally 2 -3 minutes depending on the stregth of your microwave

Answer 2

i do not know this for sure, but you can't boil water in the microwave. You can only boil it on the stove. A stove has a direct heating source. A microwave does not. it uses microwaves to move the water particles and heats the water. You can only super heat water in a microwave. The water gets really hot, but the container it is in gets really really hot, and could crack or break if microwaved long enough. You will notice that super hot water (even heated for 5 minutes) does not boil. This is just my opinion. I'd rather not try because I don't want to ruin my microwave.

Ok, heres what I found on heating water in a microwave.

The Truth:
This has been a complex one to try to track down and we've consulted a number of different sources. Here is our best understanding of the truth:
...As the millions of people who heat water in the microwave for coffee and tea can attest, this is not a common occurrence and we could find no record of injuries from it, although that doesn't mean none has happened.
...When water is heated on a stove and reaches the boiling point, there are usually the characteristic bubbles that emerge from the bottom of the heated pan. It would be easy, then, to think that all water boils like that when reaching the boiling point. The problem is, that's not always the case.
...It is possible to sometimes heat water beyond the boiling point but without the bubbles. Why are there no bubbles? When water reaches the boiling point, the water molecules need to start joining arms with other water molecules in order to create the bubble of vapor that we see as boiling. In order to do that, some molecules need to all meet together at the same place and at the same time at what is called a "nucleation site." A nucleation site can be a tiny impurity, another air bubble, even a scratch on the surface of the container.
...So, here's the scenario: Some water is heated in the microwave and both the water and the container are clean enough that there are no nucleation sites. The water temperature goes higher than the boiling point, but without "boiling." Not only that, but because of the way microwaves work, not all of the water in the cup is the same temperature. The water lining the sides of the cup becomes heated, while some of the water toward the interior of the cup is cooler

Answer 3

Well it depends on how big the cup and how much wattage your microwave puts out. My best advice is put some time on the timer and watch the cup when it starts to boil then stop it and look at the time and record it in your mind.

Answer 4

My 1000 watt microwave takes less than 2 minutes to literally boil a cup of water in a pyrex measuring cup. If I heat water for a cup of tea or hot cocoa, etc., I only heat it for 45 seconds and it's plenty hot.

Answer 5

All microwaves are different.
My advice to you is to try it out.
Put a glass of water in the microwave at first for a minute, if it hasn't started boiling, add another 30 and continue this until it begins to boil.



Good luck -Corbyn

Answer 6

It depends on the power of your microwave, 3-5 minutes should do it.

Answer 7

i usually do it for about a minute, but it depends on the strength of the microwave and how much water you are boiling. i would suggest trying it out.

Answer 8

In a 800w microwave i would say 1 minute 30 seconds should do it.

Answer 9

that all depends on how far up the mountain you live. at sea level it should take about 2 to 3 minutes. In Denver or Albuquerque it will take about 5 minutes. In Taos or Cloudcroft it will take around 10 minutes!!

Answer 10

Depending on the wattage 2 minutes is enough.
