Does it?

i would think its the fat content. fats and oils heat up quickly. then i wonder does full fat milk boil faster than skimmed?........

There really shouldn't be that much difference in their boiling points. Milk is mostly water.

Yeah I was wondering to. I'm taking chemistry now and learned that substances with higher molecular weight have higher boiling point. Milk which contains fats and other stuff for sure has higher molecular weight than water which is simply H2O, so milk should boil much slower but it doesn't. Maybe it's the high heat capacity of water?

OK, first some initial conditions: 1) the fluids start at the same temperature; 2) we're starting with an equal volume of each fluid; 3) the heat transfer to the fluid from the heat source is exactly the same in each case; 4) the fluids when boiling are vented exactly the same way; 5) we're starting with an appreciable volume of fluid; and 6) by "boil down" you mean drive off all the volatile matter in the fluid. The boiling point of water and milk are very close. So if you heat the same amount of each of them at the same rate, they'll all reach their boiling point at about the same time. The boiling point of water is 100 degrees Centigrade, or 212 degrees Farenheit; milk is slightly higher, at least at first (the milk will actually start to boil at a lower boiling point after a certain amount of evaporation). So why does milk evaporate first? Simply because not all of the sample is volatile; that is, not everything in milk evaporates. So if the milk is, for example, 5% non-volatile, and you start the experiment with 1000 grams of each fluid, you need to make 1000 grams of the water and the vinegar evaporate, but only 950 grams of the milk. http://www.madsci.org/posts/archives/feb2001/981727877.Ph.r.html

because milk contains lactosis veganus straighticum edges intolerantus it starts to boil at 66.6 degrees C. These small particles quickly becomes almost aggressive when put under heat. This is why milk often expands during heating and "boils over" or rioting. These particles also "believes" (behaves as) milk isn't for "drinking", instead just to be used as political arguments for blaming other particles and for inconsistent agendas that lack purpose. If the idea behind the creation of milk doesn't belong to "drinkables", then we should be allowed to hit women that won't do what they're told to, and women that are wearing pants should be executed in public. I have more ideas on this that are based on reliable sources.
