Question

sublimation keep naphthalene ball
plz tell step by step​

Answer 1

Answer:

Naphthalene balls are kept with cloths and documents to protect them from insects. Since naphthalene balls go under sublimation, hence it changes into vapor without changing into liquid and its vapor prevent the insects to come or stay in cloths or documents. This protects the documents and cloths to get destroyed.

We usually see that the size of naphthalene balls decrease gradually and finally disappeared when they are kept in open. This happens because of sublimation of naphthalene.

Answer 2

There is a process of sublimation that occurs where the naphthalene changes its state from solid to gas directly without changing to liquid in the middle. This is the reason why the naphthalene balls keeps reducing its size if we keep it exposed to the air and atmosphere.
