It is said that when we heat a liquid it gets evaporated. But if we heat milk why does it flow instead of getting evaporated? serious answers only.

Well, the fact is, the liquids in the milk DO evaporate. If you leave milk in a pan long enough, you're left with the solid components burning in the bottom of the pan. And that is the key. Milk contains a suspension of solids (including fats) suspended in liquid.

Milk contains over 87% of water itself. It also contains other liquids and solids too. The liquids along with water have a low boiling point and evaporate. Try heating the milk for a long time and you will see that the liquids in it evaporate. Solids have a high melting point. After melting into liquids they have to reach the boiling point in order to evaporate. This will need a very high temperature.

Milk is the most complete food, they say, and it contains a lot of 'things', out of which water is the major component. So, when we heat milk, only its liquid components are evaporated, and the rest of the stuff in it does not, which keeps floating & flowing. That is why milk seems to you to be flowing.
But even then, if you heat milk very strongly, say you boil it for 2 hours continuously, (give it a serious go someday!) you would find that most of the milk is gone & what remains is a black mass, which is the solid & semi-solid components of milk that has been burnt.

Milk is made from water and various other things.
When you heat milk, water evaporates off the surface of the milk, leaving the other components behind. The milk gets thicker. If you did this long enough, all the water would have gone and you'd be left with a sticky substance.

The process of evaporation still goes on but very slow due to other contents including water.After the water content from the milk totally gets evaporated what remains will burn if u still heat the milk.

What? If i heat milk, it (or rather the water content) evaporates. Where else does evaporated milk (like you buy in cans) come from?

Milk does evaporate, just at a higher temperature than water.

They are not made up of the same fluids.
Water is a clear liquid.
Milk has fat, proteins, and other things, it boils = cooks
