Hey dear,

I think you want to ask why zinc oxide is yellow when hot.

● Answer -

Zinc oxide

● Explaination -

- Zinc oxide is normally white in colour.

- But when heated, it gets converted to zinc metal and becomes white in colour.

2ZnO --> 2Zn + O2

- Oxygen gas is evolved in this reaction.

Hope this helps you.
