Why is my milk bubbling?

Milk contains proteins. These proteins are long, string-like molecules that form a network in the bubble reducing its surface tension. Less surface tension lets the bubbles last longer, making it easier to fill the glass. The amount of milk fat can also have a big impact on this.

What happens to milk when you heat it?

When the milk was boiling What did you observe?

When you boil milk, the temperature rises well above 100C because the water has sugars and other molecules dissolved in it. As all jam-makers know, the higher the sugar concentration, the higher the boiling point. Hence, while the milkpan is being heated, the gas’s temperature is well above 100C so it is invisible.
