Question

As shown in the figure, if the camphor is heated for 5 mins, will the residue remain in the evaporating dish? what kind of compound camphor is?

​

Answer 1

Answer:

When we heat camphor, it does not melt or becomes its liquid form, it gets converted into gas. This process by which a substance directly converts into its vapor state without changing into liquid state is called sublimation. Therefore all camphor evaporates directly into vapor state leaving no residue behind
