Best answer: Why milk boils over if left unattended?

This layer eventually becomes so thick that water vapor rising through the milk can’t break through very easily and gets trapped.

Why does boiling milk spill over the pan if we leave it on the heat?

When milk is heated further, the water vapour expands, pressure builds up and lifts the creamy layer up and thus the milk spills out.
