What happens when you heat water in a microwave oven on maximum power?

Answer 1

No, it doesn't just boil. It can become superheated and practically explode when you put something into it. See this link: http://www.phys.unsw.edu.au/~jw/superheating.html

Excerpt: "
There have been many reports of injury to people using microwave ovens to heat water to make hot drinks. Water heated in a microwave oven may be superheated and when objects (e.g. a spoon) or granulated materials (e.g. instant coffee) are put into it, the water may boil very vigorously or even appear to explode out of the container. The vigorously ejected boiling water can cause serious burns. Sometimes even the act of taking the container out of the oven and or putting it on the bench can cause the boiling.

Answer 2

Microwaves have a wavelength about the same as the vibration modes of a water molecule therefore it heats water much better than other substances, say rubber.
Think about when you push a swing, push at the right time just a little bit and you can make the swing go higher and higher, that's the idea behind resonance. Every oscillating system has a resonant frequency, the resonant frequency of a water molecule bond is equal to the frequency of microwaves.

Answer 3

26. Prostitutes always look like Julia Roberts or Jamie Lee Curtis. They have expensive clothes and nice apartments but no pimps. They are friendly with the shopkeepers in their neighbourhood who don`t mind at all what the girl does for a living.

Answer 4

The water molecules vibrate quickly, the resulting friction causes anything that contains water (or other polar molecules) to heat up

Answer 5

Uhhhh, it heats up to 212 degrees F after a few minutes.

Answer 6

You'll have to buy another microwave oven if you do.

Answer 7

it boils in high temp and may at times spoil the system too
