How would a microwave oven heat ice versus liquid water?
October 31, 2007 10:24PM
The actual process of heating would be exactly the same. Microwave energy would begin to excite molecules of water, making them move more quickly and heating them up. Eventually the ice would melt, then boil. The water would heat up then boil.
What is the temperature of Microwaved and boiled water?
With the microwaved water, it pretty much depends on the microwave Owens temperature. Though boiling water is 100 degrees Celsius. (I would like to add): The water's temperature depends how long the microwave runs and the power of the microwave. However, if the water is boiling in the microwave, it is the EXACT same temperature as water boiling on the stove. The microwave is just another method of boiling the water.

Asked in Eggs (food)
How can you make boiled eggs in the microwave?
You can not make hard boiled eggs in the microwave. If you were to put them, in the shell in the microwave they would explode and you would have a mess to clean up. Boiling is always done in water. You could still cook (microwave) them but you will have to take them out of the shell and put the egg in a cup, loosely covered .

Asked in Chocolate, Milk, Hot Chocolate
Why should you put milk in the microwave before stirring in the hot chocolate powder?
Dissolution definitely happens easier when the liquid is already boiling, however, I personally believe that 'more time inside liquid' is better for dissolution and ALSO that microwaves will hit the water molecules within 'clumps', causing them to break down better with stirring after rather than the scenario that you add the powder and then stir. If you're boiling on a stove, this benefit would not be present and clumps would stay near the top as the liquid near the top would be the coldest. Re: microwave, in either case you will be stirring after it leaves the microwave; my argument centers around the fact that both microwaves and 'time in liquid' cannot HURT dissolution. The opposing argument will claim that the clumps will becoming clumpier the longer they are in the liquid without being stirred. This just seems silly to me.
