Question

I was wondering that like whenever I boil milk I just have to keep standing in front of it to make sure that I don't waste any milk but then I was wondering like Why does it even overflow ? In case of water it doesn't happen. What makes it to behave like this ?

Answer 1

Answer: Milk is an emulsion of fat and water. When you boil milk, the fat separates to the top and forms a layer on top.
