Nucleate boiling is a condition in which bubbles of steam nucleate at points on a metal surface and minute concentrations of solids develop at the interface of the bubbles and water.

The simple answer is when we put water on the heated plate then sudden water converted in vapours with bubbles that is nucleate boiling.

No, @Adarsh you are wrong. In film boiling, bubbles form more rapidly so that they coalesce into a vapour film that insulate the heating surface & preventing the inflow of fresh liquid. Film boiling is not generally desired in heat transfer equipment.
