Let's note some observations.
When water is boiled, the liquid water gains thermal energy, becomes steam, comes to the top as bubbles and burst to go into the atmosphere.
Similarly, when milk is boiled, the water turns to steam bubbles which move to the surface of the milk in the form of bubbles. But they cannot burst to the atmosphere easily because of the layer of fat on milk. The bubbles moving to the top continue to push the fat layer due to their kinetic energy. They cannot burst since they the pressure inside the bubble is less than that of the outside. When the fat layer surpasses the vessel walls, it results in the overflowing of milk.
If you boil the milk after once allowing it to boil over or removing the fat layer, the boiling will induce overflow with lesser intensity when compared to that with the the fat present. The lesser boiling over takes place because of the remaining fat in the milk.
Water does not boil over because it does not have any top layer which prevents the bursting of gas bubbles.
When water is boiled it changes from liquid to a gas.
No. It will affect the distance the water rises, but not the volume of displacement.
Steam from a ton of water boiled away to nothing.
Although you might think milk fats would likely float on water, milk also contains other solids like proteins and sugars, which make it barely heavier than water. So usually no - at the same temperature and pressure, ordinary homogenized cow milk would sink in water. A gallon of milk is heavier than a gallon of water.

You can drink boiled water not boiling water if you like to drink boiled water you can add a coffee or milo and even milk :)
Milk overflows when boiled for the first time because it contains entrapped air. The air expands on heating and tends to escape lifting the surface of milk. Once all the air is expelled, the boiling would be regular and smooth.
No, when milk boils, it is only the water which evaporates. The various substances dissolved and emulsified in the mixture stay behind. If you condense the vapour you will get water.
Milk is more acidic when boiled. The normal acidity (pH / Power of Hydrogen) of milk is usually 6.5 and 6.8, but when boiled, the pH can decrease to around 5.7!
milk which is not boiled.....
No. Pasta is basically boiled in water. Although, if you would like to make macaroni and cheese, I suppose one of the ingredients would be milk.
Skim milk is about 5.1 to 5.4.
Yes. The water may be boiled off or evaporated by heating in the usual manner, and then collected on glassware.
I think you mean "Porridge" and it's made from oats or other grains boiled in a liquid such as milk or water.
No, boiled water is simply boiled. Distilled water is when the steam from the boiling is gathered and rebottled.
Boiled water.
Probably the same as before you boiled it. I think boiling doesn't alter the fat content of milk. Milk is about 3.9 grams of fat per 100 grams of milk
